What term refers to experiences that occur without external stimulus with the full force and impact of a normal perception?

• A. Auditory Hallucinations
• B. Hypnopompic Hallucinations
• C. Hypnagogic Hallucinations
• D. Hallucinations

Answer: (D)

Experiences that feel real but occur without any external stimulus are called hallucinations—the sensation is as vivid as a real perception, but there is no actual sensory input. This can involve any sense, such as hearing, seeing, smells, or touch. The question describes the general phenomenon, so the broad term that covers all such experiences is the best fit. The other options specify particular kinds: an auditory hallucination is limited to hearing; hypnagogic and hypnopompic refer to hallucinations that occur at sleep onset or upon waking.
