My dreams usually don't make any sense whatsoever so I never feel I need an interpretation. But this dream was so close to what is actually happening in my life that I want to know the significance.
Background~my 33yr marriage appears to be over. My spouse has a new love and though we still live together he spends more time with her than home with me. He recently said that he doesn't feel that this new relationship is very stable and is almost exclusively physical. He says he doesn't want to divorce but I never see him and I recieve no affection from him.
Dream ~ I come into our house which is not well lit (maybe evening time) and my spouse is sitting in the dark crying inconsolably. I embrace him and asked what happened. He says she doesn't want him and has found someone else. He is devastated. I try to comfort him and continue the tight embrace. I tell him I understand what he is going through and I know how much pain this is for him. He says he is very grateful to me for staying with him and for being there for him now. The dream then skips to a different scene. I'm in a car talking to him on the phone. Its still dark (maybe dusk or heavy clouds) We are talking about how much better our relationship will be now that we have survived this event. I am feeling so wonderful about the relationship and I can't wait to get home to see him but instead of driving I park the car and get out and start running home. I'm naked except for a bra. When I get home our adult daughter is there with him and I accidentally let it slip about the affair. He looks at me very hurt that I exposed him to her but the feeling is still one of love for me. I woke up at this point and the feeling wonderful about the relationship stayed with me through the morning even though in waking life it's looking like that relationship is getting stronger while ours is getting weaker and less important to him. He spends almost every weekend with her while I am home alone. I don't know if it is significant but the color in the dream is extremely desaturated. Not black and white just faded color but with contrasty lights and darks.

Is this just a reflection of what I want to happen? Why am I naked but with a bra?
Why would I park the car and start running.. if I'm in a hurry to get home to him wouldn't it be quicker to drive?

Yes, there could be some unconscious wish fulfillment in there. But when something as big as this is going on in your life, you are bound to have conflicting feelings, so there is just a part of you that wants your dream to come true and probably a part of you that wants the opposite.

Travelling in a dream often has to do with the path you are taking in life, so getting out of the car and running could have to do with realising that if you want to get what you want out of life, you are going to have to take a different approach; you can't continue doing what you have been doing, even if what you have been doing seems easier.

Being in the car could also be associated with being trapped; you need to get outside.

Wearing the bra and nothing else could have to do with being supported. You are feeling safe and comfortable because the bra is supporting your breasts, but in reality you are vulnerable and exposed, because your genitalia are uncovered. I think that part of the dream has to do with having a false sense of security.

The faded colors in the dream could have to do with you having numbed yourself to your emotions.
