In high school I slept in my parent's basement, and one night I felt this little tickling on my chest. I thought... nah it's nothing don't be paranoid. Then I felt it tick again. I slapped my hand down and felt this mash of giant limbs against my chest. I awoke to find that I had crushed this huge wolf spider onto myself. You have no idea how much that traumatized me; every night for the next year every single itch or whisp against my body scared the shit out of me.
