illusory
deceptive / unreal / misleading / imaginary
Adjective
This term describes a perception that is fundamentally disconnected from reality, often implying a deceptive quality that lures the observer into a false belief. It carries a stronger sense of total falsehood than words like misleading, suggesting that the object or feeling exists only in the mind of the perceiver. In professional or psychological contexts, it often refers to cognitive biases or false hopes that provide temporary comfort but lack any grounding in fact. It is typically used with a negative or cautionary connotation, highlighting the inevitable disappointment that follows the realization of the truth.
