Blatantly stolen from the random creepypasta section of http://scp-wiki.wikidot.com/
When I showed this to my wife, she spent the next 2 days asking me "You'd tell me if this was real, right?"
"It has been reported that some victims of rape, during the act, would retreat into a fantasy world from which they could not WAKE UP. In this catatonic state, the victim lived in a world just like their normal one, except they weren't being raped. The only way that they realized they needed to WAKE UP was a note they found in their fantasy world. It would tell them about their condition, and tell them to WAKE UP. Even then, it would often take months until they were ready to discard their fantasy world and PLEASE WAKE UP."
Comes in at the low 90's word count. For bonus points, de-capitalize all the wake ups and make them subtly different. A slightly off-black color of print, make font size 11 in a font 12 paper, etc.
For super bonus points, tailor the final wake up to your professor. If the professor is female, hand-print the words "they finally caught him, honey, please wake up. Love -dad." in a bold, legible pen. If they have a child, make it "Mommy/Daddy, I miss you, please wake up" in barely legible crayon.
