What do hallucinogens primarily distort in an individual?

Hallucinogens primarily distort sensory perception in an individual. These substances can cause users to experience altered realities, where they might see vivid images, hear sounds that aren’t there, or even feel sensations that don’t exist. This means that the way individuals perceive their surroundings can change dramatically, leading to experiences that are not based on the actual physical environment.

For example, someone under the influence of hallucinogens might see patterns or colors that don't exist or hear music or voices that are imaginary. This distortion of sensory perception is a hallmark of hallucinogenic experiences and is a key reason why they are classified as such. The other options, while they can be affected indirectly by the overall experience, do not specifically center on the primary effects noted with hallucinogens.
