TERROR IN THE HAUNTED HOUSE 1958 PSYCHORAMA DVD
Psychorama, also called the precon process, is the act of communicating subliminal information through film by flashing images on the screen so quickly that they cannot be perceived by the conscious mind.
In 1958, a film called My World Dies Screaming (later retitled Terror in the Haunted House) marked Hollywood's first attempt to make use of this technique. At different points in this film, a skull is flashed to inspire terror, a snake to inspire hate, two hearts to inspire love, and large letters spelling out "blood" to create fear. The following year, 1959, saw another film produced using this same format, titled A Date with Death. Both movies starred Gerald Mohr.
