Auditory Hallucination
RisksA perceived sound with no external source — voices, music, tones. Reported far less often with classic psychedelics than visual hallucinations are, and more associated with other conditions when it does occur.
Example: There's a mechanistic reason for the gap: psilocybin's visual hallucinations have been traced specifically to 5-HT2A receptor activation altering visual-cortex processing (measurable as changes to alpha brainwave oscillations and visual-evoked potentials), a well-studied pathway that doesn't have a clear auditory equivalent — classic psychedelics simply don't reliably drive the auditory system the same way.
