Yeah, I had a dream series once. Unfortunately, it was a two-night affair, and the second night made very little progress.

Sometimes, I'll be dreaming (usually my grandpa's in it for some reason), and I'll think, "Hey, wait a minute, I've had this dream before!"

Also, I'll dream something--usually some random tidbit that makes no sense at the time--and then it'll happen in real life. I never realize it until after it's done and over, but I'll find that as people say stuff, it triggers a memory of them saying it in the dream. Sadly, I can never seem to fast-forward enough to know what they'll say next in real life, but it's pretty freaky.
