This happened when I was 5 lol I don't remember anything but getting in the box with my eyes closed and then opening my eyes to find myself sitting up against a door (I hit my head on the door hinge and busted my head open) of course, I didn't feel s[ ]t bc adrenaline lol
So here's what happened: I was trying to get in a box (because I was pretending it was a swimming pool-) and I grabbed this stool, got on top of it, and closed my eyes (I was terrified of heights as a kid) and jumped in. Then goes the whole 'hit head against door hinge' thing (mind you, I had apparently gotten a mind-block or something, or I disassociated, because no memory). Come to find out I was trying to get OUT of the box and hit my head on the door hinge in the process. Kinda got knocked out for a second and then I wake up and I'm sitting up against the door, not feeling anything, and with my head busted open. Went to the hospital, had to get staples. Because I was so young, it didn't scar.
