Dream (astral?) Sex

I "woke up" this morning to still find my boyfriend at my house. We were getting frisky, and it felt really real--and then I realized I was in a dream. At the same time, he was asleep on the train to work, and later told me he "woke up" and found himself w/me at home getting frisky.

I think this was some sort of astral thing. It was really neat.
