From Beyond

Humans are such easy prey. The Resonator, a powerful machine that can control the sixth sense, has killed its creator and sent his associate into an insane asylum. But when a beautiful psychiatrist becomes determined to continue the experiment, she unwittingly opens the door to a hostile parallel universe... and to the deviant behavior within the human psyche. With its victims becoming creatures who feed on - and become aroused by - human brains, the Resonator is the ultimate man-made monster. And now something's gone horribly wrong and no one can turn it off!
