I had an idea about a framed picture witch can distort reality, cause people to go insane and such when viewed. It is (in my mind) a framed 20 by 15 cm picture of a mans face. It is black and white and the man in the picture is unidentified. He seems to have high cheek bones, eyes set wide apart and thin lips. He also has no hair.
When a person is viewing the picture, directly or if it even just fits in the persons field of view, the world around the person changes only to them. They're surroundings become heavily distorted. Persons who have viewed the picture report to have seen things far more terrifying than their own worst nightmares. The illusions are so incomprehensibly evil and scary, people who are questioned simply go into a state of shock and eventually faint.
Persons who have viewed the picture were only able to report one thing and that is that the eyes of the man in the picture started bleeding. Also, that followed, were strange, in comprehensive noises witch were described as "the worst sound nobody should hear".
That is, in short, "The Oblivious One". I will be waiting for some feedback. Feel free to add to this idea if you have your own.
