non-sensory hallucination
   A term used by the British paranormal researcher Edmund Gurney (1847-1888) as an umbrella term for normal acts of the imagination or memory, such as remembered * images, * daydreams, and mental pictures, which all lack an actual perceptual quality, and have no objective basis in the extracorporeal world. Gurney uses the term non-sensory hallucination in opposition to the term * sensory hallucination, which he reserves for a percept which lacks the objective basis which it suggests, whereby that lack can only be recognized by distinct reflection.
