Individuals with exploding head syndrome hear or experience loud imagined noises as they are falling asleep or are waking up, have a strong, often frightened emotional reaction to the sound, and do not report significant pain; around 10% of people also experience visual disturbances like perceiving visual static, lightning, or flashes of light.
Hori et al. regard sleep onset hypnagogia as a state distinct from both wakefulness and sleep with unique electrophysiological, behavioral and subjective characteristics, [10] [12] while Germaine et al. have demonstrated a resemblance between the EEG power spectra of spontaneously occurring hypnagogic images, on the one hand, and those of both ...
These three categories do not account for all types of auditory hallucinations. Hallucinations of music also occur. In these, people more often hear snippets of songs that they know, or the music they hear may be original. They may occur in mentally sound people and with no known cause. [5]

A hallucination is a perception in the absence of an external stimulus that has the compelling sense of reality. [6] They are distinguishable from several related phenomena, such as dreaming (), which does not involve wakefulness; pseudohallucination, which does not mimic real perception, and is accurately perceived as unreal; illusion, which involves distorted or misinterpreted real ...
In response to audio stimuli, the mind's way of interpreting sound can be translated through a regulatory process called the reticular activating system.Located in the brain stem, the reticular activating system continually listens, even throughout delta-wave sleep, to determine the importance of sounds in relation to waking the cortex or the rest of the body from sleep.
