Scientists "see" ghosts

According to The Telegraph: Why do apparitions, bogeymen and phantoms like to lurk in the shadows? Scientists may have the answer. A team from University College London finds that when we gaze around in a poorly-lit context, it can fool our brains into seeing things that are not really there. Nobody has done a systematic study of ghosts, but computational biologists are convinced they are "all in the mind" and, in the light of the new work, it does not seem so surprising that they seem most often glimpsed in "spooky" dimly-lit circumstances.
