Apparitional experience
In parapsychology, an apparitional experience is an anomalous experience characterized by the apparent perception of either a living being or an inanimate object without there being any material stimulus for such a perception. In academic discussion, the term "apparitional experience" is preferred to the term "ghost" because: The term ghost implies that some element of the human survives death and, at least under certain circumstances, can make itself perceptible to living humans.
