What type of perception do hallucinations involve?

Hallucinations are defined as false perceptions that occur without any corresponding external stimuli. This means that individuals experiencing hallucinations perceive things that are not actually present in their environment. For instance, someone might hear voices, see things that aren’t there, or feel sensations that do not have a physical source. Unlike accurate sensory experiences, which correspond to real external stimuli, hallucinations represent a disconnection between perception and reality, emphasizing that these experiences exist solely within the mind of the individual.

The other options do not adequately capture the nature of hallucinations. Accurate sensory experiences involve perceiving actual stimuli from the environment. Recollections from memory do not involve direct perception but rather the retrieval of past experiences. Clear thoughts of reality suggest a grounded understanding of one’s surroundings, which is contrary to the essence of hallucinations where perceptions do not align with reality.
