In an effort to test whether or not it's possible to artificially induce paranormal experiences scientists have created a "haunted room" filled with high electromagnetic fields, infrasound waves and other experience inducing effects.
"Fake blood, canned screams and plastic skeletons are fun, but if you want a real haunted house, turn to scientists. To test whether it’s possible to artificially induce paranormal experiences — or, from a different perspective, to technologically summon a spirit — researchers at London’s Goldsmith College and architect Usman Haque designed a scientifically haunted room."
