The dream seems to repeat a few events... a woman being cold, and then receiving warmth, protection and shelter, and driven by someone else.
The first time it's a character in your dream (the old woman at the bus stop), the second time it's you it happens too. That this pattern repeats indicates it's significant to understand it.
You mention first how you moved life in a new area... that is almost like a symbolical word "pun"... are you starting something new in your life? The dream shows how you feel in this situation... unfamiliar and alone. The blizzard symbolizes feeling emotionally cold, feeling excluded and left out.
Roads usually stand for your life course, the road of your life. Therefore vehicles symbolize the manner in which you go through life. A bus is public transport, where you are one of the many who is driven by others. It indicates feeling being a number as well as feeling unable to take control of your life. In the dream you een have to "wait" at a bus shelter. That would then point to you are waiting for what you want in life, and the necessity for you to wait for it. It will come... the bus always comes... but not just right now this instant. It's a temporary setback.
So, in this lonely cold world where you have to wait before reaching your goals in life, you empathize with an old woman... empathy is a way to try and connect wth people, but it's also a projection process. You can well imagine how cold she must be, because the blizzard indicates that is how you feel inside too. So, I'm wondering whether there's another trait you empathize with... do you consider yourself as growing old? Do you fear it's too late to have the things in life that you want?
You give her everything you have to keep her warm, but then she's picked up and driven away, and once again you're out on your own, alone, and colder than before in the dress without a coat and all. It's almost as if you feel colder because you realize that you gave everything to the other and yet saw no return, nor care for you. They accepted your help, and offered none in return.
And yet, there's a man who offers you shelter, warmth and protection... (like a pay it forward principle). Your snuggle and sleep reaction indicates this is what you have been waiting for: a man to warm you, make you feel less alone, noticed, cared for. I would also like to note that the party dress to me says you are still young of mind and body: you still have what it takes to enjoy life, to party.
What especially strikes me though in this dream, and what I was looking out for is your position once you drive off with this man. When you are driven in a vehicle as a passenger, then you go through life rather passively... if you're driving and holding the steering wheel then the dreamer feels in control of his/her own life. In your case, you're sleeping in his lap. That is not just very passive, it's almost as if you turn into a little child who can't take care of herself. And yet, I'm sure you can take care of yourself, otherwise you would not have been able to take care of the old woman. In one way it shows a total innocent trust in this man (you can sleep), a total surrendering. But surrendering like that also implies absolute passivity.
Is that what you truly wish from a relationship? Do you want to be with a man who takes total care of you and surrender yourself that totally?
I'm thinking the dream shows you such a total surrender and passivity is not what will make you feel truly happy... For one, you end up feeling suspicious (you didn't say, but you noting how he dances with every woman but you, indicates you are specifically watching him on that note). Secondly, such a total passivity may indeed make someone take you for granted.
The ending of him going to your house to find out why you left, may be a sign that his unconscious actions were no actual threat, but the result from the relationship pattern of who's active and who's passive. You tell him in your dream that it was him who upset you, but I somehow have the distinct feeling that you were not speaking to the man, but that it was you speaking to yourself... That you are upset with yourself.
If this is what your dream means then that explains why you feel so sad: the dream expresses your feelings of isolation, your need for someone in your life to gie you warmth, but also that you feel unable to take control of your own life and you blame yourself for that.
Well here's a big hug from me
