Ontolepsia

A psychological or perceptual condition in which the boundaries between different levels of reality are blurred or indeterminate. A state of cognitive disorientation caused by uncertainty regarding what is real or imagined, often used in the context of narratives or artistic works that induce such disorientation.

“The protagonist in Inception suffers from ontolepsia, struggling to distinguish between dreams and reality.”
