Which type of hallucination occurs upon waking up?

• A. Hallucinations
• B. Auditory Hallucinations
• C. Hypnopompic Hallucinations
• D. Non-bizarre delusions

Answer: (C)

During the transition from sleep to wakefulness the brain can intrude dream imagery into waking perception. When this happens as you are waking up, it’s called hypnopompic hallucinations. The term literally means “upon waking,” so it best fits a phenomenon that occurs at that specific time. These experiences are often visual and may be brief; they can also occur with sleep paralysis or in conditions like narcolepsy, though they can occur in otherwise normal sleep as well. This differs from hypnagogic experiences, which occur when falling asleep, and from other terms like generic hallucinations (perceptual experiences without external stimuli) or delusions (fixed false beliefs).
