Closed-eye hallucination: Levels of CEV perception, What is not a CEV & Overview

Closed-eye hallucinations and closed-eye visualizations (CEV) are hallucinations that occur when one's eyes are closed or when one is in a darkened room. They are not the same as phosphenes; perceived light and shapes when pressure is applied to the eye's retina, or some other non-visual external cause stimulates the eye.
