Tactile hallucinations occur when there is a tactual perception in the absence of a physical stimulus. This creates the sensation of tactile sensory input, simulating various types of pressure to the skin or other organs. This type of hallucination is often associated with substance use, such as someone who feels bugs crawling on them (known as formication) after a prolonged period of cocaine use.
