Which word means 'imagining things that are not real'?

• A. Ubiquitous
• B. Detectable
• C. Startling
• D. Hallucinating

Answer: (D)

Imagining things that aren’t real is captured by the idea of hallucinating. Hallucinating means perceiving something with the senses—seeing, hearing, or feeling something—that isn’t actually present in the external world. It goes beyond ordinary daydreaming or imaginative thinking to a sensory experience that isn’t grounded in reality.

The other words don’t fit this idea: ubiquitous means present everywhere, detectable means something that can be noticed or identified, and startling means causing surprise or shock. None of those convey the sense of sensory experiences that aren’t real, which is why hallucinating is the best fit.
