I had a similiar dream , and luckily my therapist is psychoanalytic, does the dream interpetating thing, because I felt really ashamed and embarressed.

I'll breifly sum up mine and tell you what my therapist said:

Basically, in my dream I had sex with an underaged kid, woke up horrified.

At the time I was entering into a relationship with a friend that was starting to get sexual, and I was unsure how I felt about it all, so it translated to my wish for a sex life, but how I also felt it was not appropraite, and it was awkward in a way.

Really, it doesn't even have to be sexual-a shot in the dark here, but I think it has to do with the relationships in your life, whether you're watching one or in one. I would examine those and explore my feelings around them. Even if thinking about it ends up not resolving the out-of-character dreams (which may be the whole cause of the dream...were you forced to do something out of character, or anything dealling with that?) at least you will get the chance to take an outside perspective on the "inside" of your life, persay.

Serously, who knows, dreams are out in left feild to begin with;
if we look for similarities in something though, we usually find them.
