Most of the dreams I'm aware of are sex dreams. Probably more than 80%. Some surreal, some preposterous, some very nearly believable, most XXX. (And no, I'm not going to share details.) Obviousy these are just the dreams I wake up from, and it's entirely reasonable to expect I have lots of non sexual dreams and I don't know about them because I don't wake up from them.
It's not connected to relationship status, time of night/day that I wake, age, weather, the movie I've just watched or anything I can think of - it's been like this for decades.
I'm perfectly comfortable with this, but I'm just curious if anyone else is a compulsive sex dreamer?
