Transliminality

Transliminality (literally, "going beyond the threshold") was a concept introduced by the parapsychologist Michael Thalbourne, who was fooled in  Project Alpha. It is a trait characterised by thin boundaries between the conscious mind and the unconscious. High degrees of this trait are believed by Thalbourne to be associated with increased tendency to mystical experience, greater creativity and greater belief in the paranormal, but Thalbourne has also found evidence that transliminality may be positively correlated with psychoticism. He has published articles on transliminality in journals on parapsychology.
