Dictionary of Hallucinations

THERMAL HALLUCINATION

Also referred to asthermic hallucination. Both terms are used to denote a hallucination of temperature. Thermal hallucinations have been reported chiefly in the context of "psychotic disorder and " somatosensory aura. In both cases the phenomenon appears to be relatively rare, and seldom to occur in isolation.
