Higher levels may also manifest itself in multiple voices or even an ambiguous collection of voices such as a crowd. The speaker behind this voice is commonly interpreted by those who experience it to be the voice of their own subconscious, the psychoactive substance itself, a specific autonomous entity, or even supernatural concepts such as god, spirits, souls, and ancestors.Īt higher levels, the conversational style of that which is discussed between both the voice and its host can be described as essentially identical in terms of its coherency and linguistic intelligibility as that of any other everyday interaction between the self and another human being of any age with which one might engage in conversation with.

These can take on a variety of voices, accents, and dialects, but usually sound identical to the person's own spoken voice. Separately generated audible external responses - Externally heard conversational responses to one's own thoughts and feelings which are perceived as a clearly defined and audible voice which sounds as if it is coming from outside one's own head.These can take on a variety of voices, accents, and dialects, but usually sound identical to one's own spoken voice. Separately generated audible internal responses - Internally heard conversational responses to one's own thoughts and feelings which are perceived as a clearly defined and audible voice within one's head.Separately generated internal responses - Internally felt conversational responses to one's own thoughts and feelings which feel as if they are generated by an entirely distinct and separate thought stream that resides within one's head.Mutually generated internal responses - Internally felt conversational responses to one's own thoughts and feelings which feel as if they are partially generated by one's own thought stream and in equal measure by that of a separate thought stream.This sensation is often referred to within the scientific literature as a "sense of presence". A sensed presence of the other - The distinctive feeling that another form of consciousness is internally present alongside that of one's usual sense of self.

This voice is often capable of high levels of complex and detailed speech which are typically on par with the intelligence and vocabulary of ones own conversational abilities.Īs a whole, the effect itself can be broken down into 5 distinct levels of progressive intensity, each of which are described below:

Main article: Autonomous voice communicationĪutonomous voice communication (also known as auditory verbal hallucinations (AVHs)) is defined as the experience of being able to hear and converse with a disembodied and audible voice of unknown origin which seemingly resides within one's own head. This effect can be broken into specific sub-types which are described and documented below: However, they can also occur less commonly under the influence of stimulant psychosis, cannabinoids, and during sleep deprivation. They are most commonly induced under the influence of moderate dosages of hallucinogenic compounds, such as psychedelics, deliriants, and dissociatives. However, at other times, auditory hallucinations may also present themselves as consisting of completely novel and alien sounds that are unlike anything which could currently occur within the external environment.Īuditory hallucinations are often accompanied by other coinciding effects such as auditory distortions and auditory acuity enhancement. For example, a person may repeatedly hear a knock at the door when they are expecting a visitor or may hear music which they were listening to earlier on in the day. In terms of their behaviour, these sounds will often be based on noises which were expected to occur or have been genuinely heard on a frequent basis within the external environment.

The most common examples of this include hearing clips of sound such as imagined music, voices, tones, popping, and scraping, but can also be an infinite variety of other potential noises that are stored within one's memory. An auditory hallucination is the experience of hearing spontaneous imaginary noises.
