The only one that comes to mind, is going to some party and having my way with the hottest guy. No matter how much he fought, I still had my way. I locked him in the bedroom, tied him down.... was lots of fun.
Yes, I remember once when I was younger I had a dream I was in a really big, dark library in NYC. I really sensed something bad was about to happen and I was scared out of my mind. I remember "knowing" I was in a dream, and I kept trying to wake up.
I do it quite often, it usually happens when I wake up in the morning then fall back to sleep. If it's a lazy day I'll have about 2-3 of them. The sexual ones are quite interesting,
