Tactile hallucination (pronunciation: /ˈtæk.taɪl hə.luː.sɪˈneɪ.ʃən/) is a type of hallucination that involves the sensation of touch or movement in the absence of external stimuli.
Etymology
The term "tactile hallucination" is derived from the Latin word "tactilis" meaning "able to touch" and the Greek word "hallucinari" meaning "to wander in the mind".
