my roommate keeps telling me our house is haunted

this is him: "oh but sally downstairs said the woman who lived here two tenants ago was murdred!!!!" (said in whiny scared boy voice)

me: "if i were dead i'd haunt a nicer place than this rat infested dive". (said in annoyed girl voice)
 
i actually already have a plan about who will be haunted. but if i can somehow work between two places... well consider it done.
 
you should paint creepy shapes in glow in the dark paint on the walls, then paint over it in a watered down coat of the normal color(works well with really light phos paint and a thin coat of white :)), so once the light are turned out, there will be shapes on the walls that fade after a minute, then if they turn the light on for only a few minutes they won't be there, but if they keep it on for a while they'll reappear :D
 
the last thing i want is my roommate bugging out more than he already does.

him: "What was that noise?"
"did you hear that?"
"was that in here? or outside?"
