I have a fear of Slenderman coming out of the closet in my spare room and then ghosts coming out of the window... yeah kinda weird, but I have some ways to face my fears:
-Pack that closet full of boxes and stuff
-Do tons of stuff in there, like I set up my laptop and fan in there and play Feralheart and all sorts of stuff, and then I have my cello in there that I need to practice.
-Wonder how Slenderman would even get in my closet
-At night I keep the lights off to show myself that they're not there
Yeah, weird fear, weird ways to overcome it XD
