A strange dream that I once had was that I was on some kind of a bridge thing, and then I fell off, and plummeted to the ground (which was roughly 5 metres below me), and when I was just about to hit the ground, I suddenly woke up, sweating.
I also remember when I had a very long nightmare when I was four, I was sleeping in my parent's room, next to my mother and when I feel asleep, I woke up in some sort of weird place with many, many floors, and monsters that looked like yetis roaming the area, so I got scared, and ran away, then I had a vision in my dream of an army of scorpions going through a restaurant and literally eating the skin off a waiter! Then I woke up in my parent's room, or at least that is what I thought, the room was all dark, and then my brother appeared, somewhat looking like Cupid the fairy, and he gave me a bow, which instead of Love Arrows, held Crayon arrows, then I was just about to win some sort of a game, so I moved to the exit and feel into a pit of poisonous acid...
I woke up crying, and I don't know how it happened, or how I remember it so well.
