The killer-bed frame
An ancient oak tree driftwood bed frame with unintelligible language with a mix of all languages scribbles, lettering, and symbols on it carved in. Whoever purchases it will be under its lure making them bump into it and trip over corners while causing injury until one day it makes you dive your forehead into a very sharp corner ending in the owner's death and whoever it's left to or if someone buys it the bed frame will do it's thing all over again.
