Once i was talking to my mom in the kitchen. The doors to it were closed. I was going to go out, so i walked towards the doors. When i was almost there, i suddenly couldn't see a thing. Everything went pitch black. I started screaming, then i felt really dizzy and fell to the ground.
This felt nothing like fainting, i've done that millions of times. This was strange.
I used to sleepwalk. We lived in this really old house during the summers when i was a kid. I got this whole floor just for myself. There were two big rooms, one kitchen and one small room, where i'd usually sleep. Between those rooms was a tiny space, around 1m X 0.5m . Below this space was a really steep staircase. I used to walk back and forth this space, just over the stairs. Nothing really happened to me, though. But my parents always woke up because of the noise the house makes when someone walks around
