Auditory hallucination

Auditory hallucinations can be described as spontaneous imaginary noises that are either triggered at complete random or manifested in the place of noises that are subconsciously expected to happen. The most common examples of these are usually experienced as clips of recorded sound, such as imagined music or voices, and an infinite variety of sounds that are stored within the brain.

This effect can be broken down into 4 distinct levels:

1. Partially defined, embedded hallucinations - At this level, the sounds are partially defined in their clarity meaning that they sound indistinct, muffled, and difficult to make out. They are strictly heard only embedded within genuine sounds produced by the external environment. For example, one may hear music in the sounds of the wind, cars, and rain.
2. Partially defined, separate hallucinations - At this level, the sounds remain only partially defined but become heard on a separate layer of their own instead of only manifesting themselves within other noises.
3. Fully defined, separate hallucinations - At this level, the sounds become fully defined in their clarity, meaning that the specific words being spoken or musical content of the hallucination can be recognized and understood perfectly.
