Using humidity, temperatures and electromagnetic and sonic frequencies that parapsychologists have associated with haunted spaces, this projects aims to building an environment thet feels "haunted": a non visual architecture. A circular featurless chamber was built inside a standard apartment in London. The temperature was 18 degrees celsius and the light level was 1 lux. A purpose built infrasound cabinet and two electromagnetic coils provided varying stimuli. haunt is a collaboration with Professor Chris French of Goldsmith College Psychology Department.
