I talk in my sleep, talk back if asked something, sit in my bed, I don't think that I ever got out of it, at least never when someone else was sleeping in the same room.
As for the dreams part, here are some of my gems.
Last year I was dreaming about having sex with myself, like an older version of myself but in my dream I thought of her as of my friend. It was really sensual and I liked it. Too clarify something about this, I do appreciate woman's body and beauty but I'm not bisexual, so this was a strange thing for me to dream, let alone the part that both persons were me in fact.
And during last fall I had a series of dreams of being pregnant, where every dream was of pregnancy closer to giving birth and finishing with the dream of actually giving one. Every dream was extremely colorful, vivid, full of smells, different sensations, and the final one about actual birth was even painful to some extent. I wasn't scared, but excited. To clarify this one, I never gave birth and I'm not planing pregnancy so this made no sense to me.
One of my most recurring dreams is about wide, deep, slow and fresh water rivers. Sometimes I'm bathing in one, sometimes I'm just sitting by one, or some part of my dream in general takes place near one. For me this dreams are very pleasant, I like them the most, they have extremely calming effect on me, and recently I started dreaming rivers again. It's been a long time since last time dreaming about one or at least remembering about dreaming of one.
