I've had lucid dreams before, though only really for a few moments until I forget that it's a dream and play along with it again =/ My method of finding out is basically "Try to make yourself float in midair. If it works, you are dreaming".

One time, though, I started running and jumping from roof to roof, just 'cause I knew I could.

Anyway, I once had a dream where I woke up and got out of bed, and walked down the stairs where the front door was open. I got the newspaper and pulled it in, and then shut the door because it was raining (but yet, still sunny, come to think of it) outside. I left the newspaper on the floor and went back upstairs, and went to the bathroom when all the sudden I feel something wet on my side. I look and I've got this big bubble of blood on my hip, so I start freaking out and get into the bathtub trying to stem the flow. And then I woke up.

The one I just had, I was at this small Asian festival thing being held at my old elementary/middle school. I was talking to my friend on a computer or something there, and thinking I'd invite her to come, but then I remembered that she was probably still in Australia, so I decided against it. Then... I somehow ended up in a room with a bunch of kids from my high school, and I was trying to talk to a friend, but she was just looking at this drawing, so I think I gave up after a while and started drawing my own pictures. I remember looking around the room and seeing these kids gathered around a hardcover book, talking about Bleach (the show D: ), and shouting to them, "So someone got the art book, huh?". I think... someone came over and looked at my pictures I was drawing, when all the sudden some adult tells us we have to run past the playground. So I follow along with the other kids and run past the playground when I find out that we were apparently supposed to go get a kid from the playground on the way, and I remember wondering why they failed to mention that, and why we had to get a kid from the playground at all. And then I woke up.
