My cousin told me she has seen a GHOST. This is the story she told me

So, her mother was in the toilet. She was pooping and left the lights off. Her father was at work and her sister doing idk what, and then the door that was completely closed opened. She said she saw a somewhat Slenderman, but he was wearing black pants, a white shirt and his skin was black. After a second he closed the door again.

I laughed at the story because I always laugh at creepy stuff-
