Which symptom involves sensory experiences such as seeing or hearing things that are not real?

• A. Seizures
• B. Hallucinations
• C. Bleeding (Hematologic)
• D. Depression

Answer: (B)

Hallucinations are perception-like experiences that occur without an external stimulus. They involve senses such as seeing or hearing things that aren’t real, and they can affect vision, hearing, smell, taste, or touch. Visual and auditory hallucinations are the most common and often appear in conditions like schizophrenia, delirium, or certain substance-related states. This makes them the best fit for describing unreal sensory experiences. Seizures can cause temporary sensory disturbances, but they are episodes of abnormal brain activity rather than ongoing unreal perceptions. Bleeding is unrelated to perceptual experiences, and depression—unless psychotic features are present—does not primarily present with such sensory phenomena.
