hallucinate
Perceive nonexistent things
To hallucinate is to perceive something that isn't there—seeing, hearing, or sensing things without external stimulus.
Hallucinations can result from mental illness, drugs, fever, or sleep deprivation: She hallucinated spiders crawling on the walls.
In AI contexts, hallucinate describes when a system generates false information presented as fact: The chatbot hallucinated a citation that doesn't exist.
