Body In The Mattress
Guests checking into a hotel room sometimes complain of a serious stench coming from the mattress. According to the myth, a rotten corpse could be hidden underneath the mattress or within it.
The premise of Slender-Man is quite believable, though the spirit itself is not. Slender-Man is said to dwell within the darkest depths of the woods, waiting as a faceless, tall man in a black suit. He is said to abduct children.
