Mysterious Screaming Man

This doesn't really qualify as a ghost story but its pretty freaky all the same. A few years ago, when my uncle Gary was moving in we were helping him unpack. A few months later when he had setteld in , he was baby-sitting me I was told to go in the lounge while he stayed in the kitchen and had a cigerette. After a while i got thirsty and went into the kitchen to get a drink of milk. I sat on the kitchen stool with my drink when I noticed a strange browny yellow mark on the wall. I thought nothing of it, I thought it must of been a splash of paint from when he was decorating. A few weeks later I had to go back again. To my amazement the brown mark had developed into the shape of a screaming man!!! I ran to tell Gary but by the time we got back the man had disappeared.
