Unfortunately, I almost never dream, and when I do I don't remember it for more than 15 minutes.
BUT, I had recurring dreams as a kid that I remember. This one falling dream where I would try to jump from this really high wall to another really high wall and I would never make it. There seemed to be lower gravity in that dream, but by the time I reached the ground I was going plenty fast. Every time I hit the ground I would feel it, then poof back up to the top to try again instead of waking up. I had a lot of falling dreams as a kid... I'm deathly afraid of cliffs now...
I had another dream that I was in the Mario Kart 64 battle level that looked like a Lego fortress (I know you guys know what I'm talking about). But anyway I would be chased by these robo cops with laser guns and they would catch me over and over and shoot me. And it HURT! Dreams definitely feel real... until you snap out of it.
