This happened to me and I got so scared I woke up.
Straight black and theres Red spray paint, you have fun spraying whatever you want, then it leaves a message insde the paint after it erases, and you read it everytime, but the message is an insultring message, like you cant even wear a bugsuit.
So you keep spraying and reading the messages, they don't bother you, then you keep spraying F U, over and over after it erases.
(I kept it short to be censored) Then you spray one final F U, and these really long bloody fingered hands swipe across your vision, then you see 'Not Anymore' and an Undead Face of a person fades in, all white and no missing flesh.
