For those that didn't catch the first page (which I suggest you might want to, because "dream theories" tend to really irritate some people and I have a little preface warning blog readers about it), let me start with the idea that the dream starts on the night that Anna passes away, which is also Peggy's birthday.
(A theme of death and renewal/rebirth)
"Let Your Conscience Be Your Guide"
(Note: Pinocchio references in Mad Men = Wanting to be a real [honest] boy verses lies that makes one "fake")
This whole iconic sitting or laying on the couch idea is a notorious symbol of our subconsciousness, and our subconsciousness is synonymous for insights into how we are feeling based on the decisions we make everyday. It plays to both our fears and our dreams --our imagination.
In Mad Men there are several instances with people laying on the couch. There's Mad Man's opening theme with Don falling through his life, but landing safely on the couch. It represents both suicidal aspects of being an ad man at this time (as it mirrors the idea of selling lies, or fantasies to people, while not being true to yourself or those you care about) and about the human capacity to "reflect" on life in general.
This is furthered by characters that go and see psychiatrists through out the series. From Betty (who also buys a lounge chaser because it reminds her of the fantasy of wanting to be Henry), Sally, Jane (mentioned only), and now in season 6 Roger, all of these characters seem to need a place to voice their concerns (or in Rogers case a pretending of lack there of).

With that I bring us to the title of this post which ironically references ideas presented in Charles Dickens' Christmas story, "A Christmas Carol". It's something that I think was profoundly and eerily expressed in the two hour season six premiere, but also presented towards the end of season five.
We open season 6 a bit in the future. Meghan has become successful landing a small role in a soup opera, but she and Don have decided to take a WINTER vacation to Hawaii (it's on behalf of a client), before returning home for New Years. Meghan and new characters, a Client and his wife who wants to advertise Royal Hawaii along with a women who recognizes Megan from her soap opera named Karen (and who has an accent reminiscent to Anna Drapers) are the only character speaking for much of the opening scene. Don is mostly silent, passive, and is complacent until he goes to bar and meets a random young blonde G.I. PFC DINKINS. who in know doubt is reminiscent to Roger Sterling. In this sense we see the Ghost of Christmas Past, as we can see what it would be like to see Roger as a young man.

Other scenes included the Francis residents where a young girl named Sandy (a little older than Sally and note Sandy plays to 'the beach') had lost her mother and has been spending a lot of time with Betty in particular, as Betty sees need to sudo-adopt her. Sandy is an interesting character, as we can see the aspirations of a much younger pre- big city living Peggy Olsen, but also because her mother's death dances around Betty, whom last season "envisioned" herself post death due to a cancer scare, and because when we first meet Betty in season one she's struggling with a loss of her mother, whom she often lies about how she truly felt about her, while also mirroring her mother by playing mind games with her own daughter, including this idea of ignoring Sally for the sake of another.
Additionally Sandy plays the violin and dreams of going to Julliard School of Music, which defies the convectional ideals of the previous time period had about the place of a women, a discussion she has with Betty in the kitchen on Christmas...Sandy soon after leaves without saying goodbye, while Betty's role in the rest of the episode is about trying to find this lost girl.

Note: The title A Christmas CAROL implies it's a story that is a spiritual song. And Sandy may also be a juxtaposition/allusion to Joan, as Joan plays the accordion. This episode, or ideas presented in it may tie back to the episode "The Gold Violin" (disillusionment). Sandy is also likely a juxtaposition/allusion to Sally, as both the idea of growing up 'motherless' and/or not being able to connect with your mother is something Sally has experienced (and so has Betty), but also Julliard has a school of Dance and not just music. Sally had practiced Ballet in younger years (this could then be foreshadowing her coming of age, leaving the nest) . Additionally MUSIC may be something we associate with the goodness of Anna Draper, as she taught children how to play the piano and Anna may be a reference to St. Anne. ("Grace" - Mother of Mary) -And this is also contrasted with Peggy's trying to figure out a pitch for a head phone company...One could argue that wearing head phones could be a metaphor for either being in your own world and/or not being able to hear others around you.
Once back in an earlier season Don was trying to pitch an add that included young people smoking cigarettes. But what Don says is really at heart of the whole series suggesting the rebellious streak is about about children turning into adults, but really about pinning for their childhood, as they don't know yet that they're going to die.
Anna also had told Don that there is much value in young people. Telling him that they are what keep older people youthful.
Ultimately Mad Men is about facing the inevitable and fearing what comes next.
The whole thing with the death of Sandy's mother and Betty's search for Sandy is all contrasted by a the death of Roger's mother and the first time in any episode we finally see Roger have a breakdown and cry. One could argue that Betty and Roger are also similar characters in that their behavior is often child like or adolescent and that both characters are often extremely two-faced, -and both characters are often vein and spitful.
From Hell & Back


One allusion is Peggy, who again is mirroring a former Don (like the night of Peggy's Birthday) by not letting some of the people who work for her go home on New Years Eve, as it's a similar idea of Scrooge making one of his employees work on Christmas Eve Day.
Charles Dickens is also known for using whimsical names in most of his works. When you think about it many of the characters have surnames that add an additional dimension to their personal struggles with life they face, such as Lane Pryce, as a Lane is another name for street or road and Pryce is a word very close to Price, which spells out themes about values and choices: the roads taken and not taken and the cost of living certain lifestyles that include treating others poorly and/or using others for material gains...

"You Say Goodbye and I Say Hello"
This whole allusion is played through the episode, as Don is trying to create an add for a particular tropical setting, Hawaii. He's presentation features a very philosophical aspect of what Don refers to as "the jumping off point". This idea where one breaths in and out one's life in exchange for another one, as the ad features a man's suit clothes and foot prints left behind, leaving the person looking at the add to wonder or think about (in an adventurous or mysterious way), "Where did this man go?!" The client however reads it a different way, in which he feels it morbidly expresses death.
For me, the truth is I can see it both ways simultaneously, as death can be perceived as state of transition or a change ("this could change everything"), as opposed to a finalization, but it's often brushes with death that make or break us as people, as we keep searching for meaning in our lives, as the BIG questions are, "Are We Coming or are we going?" and "Is this all there is?"
Don's spiritual message in this ad also reminds me of what Harry once told Don about when archaeologists had found hand prints painted on cave walls. -How Harry believed they weren't just leaving their mark/identity behind, but also reaching out into the future. In that instance, which may stem back to this one, Don had used Harry's idea and made his for Kodak's Carousal pitch. (aka: a reinvention of the wheel /A Time Machine)
This also goes with Megan's Heinz pitch last season in which expresses something eternal from past to future, from cave man to residents of the moon, and mothers and daughters, again playing on nostalgia, leading into season 6 themes (the more things change the more they stay the same/or some things never change), and pointing out that Mad Men's themes are not exclusive to the 1960's, they're universal to all of humanity.
Do You Love Them MADLY?
Don's inspiration for his ad also ties into other things in the episode and the series. The Door Man (The episode title for 6x01/602 is "The Doorway"), whom Dr. Rosen calls Jonesy collapsed and was pronounced dead, but was revived! (Note: Jonesy is similar sounding name to Joanie, Roger's nickname for Joan) This then goes hand in hand with Don's double hanging deaths, double marriages, double floors at work, and/or double lives taken and given, something touched on in the season 5 finale with the James Bond Theme Song for "You Live Only Twice" playing in the background of the final scenes.
Lyrics for You Live Only Twice:
You Only Live Twice or so it seems,
One life for yourself and one for your dreams.
You drift through the years and life seems tame,
Till one dream appears and love is its name.
And love is a stranger who'll beckon you on,
Don't think of the danger or the stranger is gone.
This dream is for you, so pay the price.
Make one dream come true, you only live twice.
And love is a stranger who'll beckon you on,
Don't think of the danger or the stranger is gone.
Doors (and windows) are then furthered explored by Roger who tells his psychiatrist a metaphor that life is meaningless, because all it's about is walking in and out of doors -and they are all the same and where just going to one place...
This immediately also makes me think of both the band "The Doors", who are named after Aldous Huxley's trippy 1954 novel, "The Doors of Perception" in which Huxley wrote his experience while on mescaline (a mind altering drug). Huxley names his novel after a poem by William Blake, "The Marriage of Heaven and Hell", which Blake barrows "argumentation" prose which is a style well known in Dante's "Inferno" and John Milton's "Paradise Lost."
The episode also introduces a new character (mentioned a couple paragraphs ago) who lives in the same building as Don and became a social acquaintance. Dr. Rosen is heart surgeon aspiring to preform the first American heart transplant! It's a curious occupation to introduce when one considers themes about 'fixing broken hearts' (and someone else's
Note: Skies tie back to last season when a pair was given to Pete.
"This time of year can be hard." -Betty
These Are "Hard Times"
Charles Dickens can also be felt in scenes where Betty goes to try to find Sandy in the run down abandoned apartment only to find a bunch of filthy degenerate boys and Sandy's violin in case. Really the scenes are very surreal, not just because Betty can't find her and she helps the boys make something to eat, but that the scenes feel more like a dingy orphanage, which easily makes one think of "Olivier Twist". There's also a juxtaposition back to Glen when he intentionally walked into the bathroom on Betty, as Betty accidentally walks in on a young boy doing the same (And Glen once expressed that his mother was never there to take of him or sister). But the scenes are also haunting, as Betty looks through all THE DOORS of the apartment for a ghost of a girl, who has only left behind this one precious item...an item one boy says Sandy had sold to him, that Betty can't imagine Sandy would ever do, and Betty clinging onto the past of this child, almost takes the violin back home with her, but actually just leaves it outside another DOOR. At home Betty looks for solace and comfort from her own daughter, but sadly has found she too has also moved on, as Sally slams THE DOOR in Betty's face. (It's too late!)

And briefly wanting to mention Megan, her role and over all identity as a actress in the soup opera also mirrors the "exaggerated" and/or melodramatic feel the series has more and more taken.
The episode also moved around in time (which was something that started happening last season) and all of these homeless children, motherly deaths, and new characters that have familiar appearances/dialogues/situations relating to the other characters all make the episode feel like some crazy trippy manic time warp. Something like, "The Rocky Horror Picture Show". It's a future filled with super narcissism and lack of sentiment running rampant like a runaway train, and like a good Ayn Rand or Dante work, you might be left wondering how does one escape escapism? And is there a line that one can cross and never come back from? Is life really a one way street? And Is There Light At The End of the Tunnel???
Be back next week after 6x03 "The Collaborators" airs and see what it has in store for us!
Food For Thought - Allusions to LOST?

Plane crash (Mohawk/Oceanic) in association to death (Pete's father/Christian)
Island/Beaches (California, Hawaii, Korea -All locations relate to LOST)
Purgatory/Hell/Heaven - (Figurative + Hawaii "the jumping off point")
Doctor specializing in field (Surgeon: Heart/Spinal)
Main Male character in denial/spiritually confused/in the dark ('lost')
Main Male character struggles with his alcoholic/theological views of his father & Fathers Death.
Characters with Military backgrounds
Tapestry of pop culture beautiful woven together
Metaphysical.
Alternate Realities/Multiple Universe? -Dream sequences, and "trips" have been presented, it remains to be seen if my theory is right. If so, then we might see Main Male character come "full circle" through space time (Corporeal time travel & Ethereal time travel)
Note: Don's pitch with Kodak - "It's a Time Machine" = many J.J. Abrams-esque ideas, as the Island on LOST could literally be perceived as a time machine. In Felicity the character Ben Covington says the same thing about a film (Gold Rush) - "It's A Time Machine". Additionally Felicity featured both Sean recording their lives (hand held video recorder), Felicity receiving and passing messages to and from her friend SALLY (audio recorder), and Felicity time travels via magic spells and experiences 3 alternate realities by the series end.
