Hypnagogic and hypnopompic states are transitional states of consciousness that occur between wakefulness and sleep. Hypnagogic states are experienced when falling asleep, while hypnopompic states occur when waking up. These states are often characterized by vivid sensory experiences, such as hallucinations, unusual thoughts, and feelings of bodily detachment or movement.

Hypnagogic hallucinations can take various forms. Visual hallucinations might include seeing patterns, faces, or objects. Auditory hallucinations can involve hearing voices, music, or sounds. Tactile hallucinations might involve sensations of falling, floating, or being touched. These experiences are generally considered normal and harmless, although they can be unsettling for some individuals.

Hypnopompic hallucinations are similar to hypnagogic ones but occur during the awakening process. They can include similar visual, auditory, and tactile phenomena. Sleep paralysis, a temporary inability to move or speak that occurs during the transition between sleep and wakefulness, is often associated with hypnopompic states. During sleep paralysis, individuals may experience hallucinations and a feeling of pressure on their chest.

The exact mechanisms behind hypnagogic and hypnopompic states are not fully understood, but they are thought to involve the brain's transition through different stages of sleep. Neurochemical changes and the interplay between different brain regions during this transition are believed to play a significant role. While these experiences are common and usually not indicative of a medical problem, persistent or distressing hallucinations in these states might warrant consultation with a healthcare professional.
