I remember a few years ago, I used to have a dream that I was running, and then I fell into a pit (bottomless, I'm assuming). Whenever I fell in, my ears would start ringing, and I would wake up. Strange, yes?

I also remember that when I first saw Jurassic Park (I must've been around 7 or 8 years old), I had dreams that I was running through the forest behind my grandparents' house while being chased by a T-Rex. At first I would wake up before the dream ended, but I eventually got to the point where I single-handedly killed the T-Rex with nothing but a hatchet. It was awesome.
