My second one wasn't anywhere near as good or long as the first, but it still counts.

I guess I was thinking about sex when I fell asleep because that's all my dream was pretty much. Everywhere I looked, people were having sex. Everyone but me of course. It was pretty far into the dream when I just suddenly realized I was dreaming much like the first one. I was in the house I grew up in with random people everywhere. So I'm talking to this guy and we go to walk out of my bedroom when it hit me that I was dreaming. I took him by the hand and lead him back through the door. We start fooling around and I feel myself waking up. It happened so fast, I couldn't stop it.
