👉 In the context of philosophy and psychology, a hallucination is an experience that does not correspond to reality. It can be caused by various factors such as mental illness, drug use, or cognitive impairment. In some cases, hallucinations may occur spontaneously or in response to stimuli such as light, sound, or touch. The term "hallucinatory" refers to the perception of these experiences as genuine and real. It's important to note that hallucinations are not always a sign of mental illness
