Inner speech
The brain normally tags our own inner voice as self-generated; when that tagging slips, thoughts can feel as if they come from outside.

Clairaudience is the claimed ability of hearing voices or sounds beyond ordinary hearing. It has never been tested as a distinct ability.
Studies and word histories as set out below.
Clairaudience, or "clear hearing", is described as hearing messages, voices, music or sounds that others cannot — sometimes externally, more often as a distinct inner voice that feels separate from ordinary thought.

The brain normally tags our own inner voice as self-generated; when that tagging slips, thoughts can feel as if they come from outside.
Hearing one's name called or voices while falling asleep or waking is common and harmless.
The brain finds words and voices in fans, running water and white noise.
If messages contain information, write them down with the date before checking whether they prove true, and count every message. Distressing or commanding voices are a reason to talk to a doctor — hearing voices is common, and help is effective.
