Why do you hallucinate at night when you wake up?

Answer 1

Nighttime hallucinations, often referred to as hypnagogic or hypnopompic hallucinations, can occur during the transition between sleep and wakefulness. They are more likely to happen when you're sleep-deprived, experiencing stress, or have irregular sleep patterns. These hallucinations can be visual, auditory, or tactile, and are typically harmless, though they can be disorienting. They result from the brain's mixed processing of waking and dreaming states, leading to vivid, dream-like experiences.
