What is what does uncanny mean?

The term "uncanny" refers to something that is strange or unnatural, causing a sense of unease or discomfort. It often describes something that is familiar, yet somehow unsettling or eerie. This feeling of eeriness may stem from a sense of dissonance between our expectations of what should be familiar and what we are actually experiencing, or from encountering something that violates our sense of normality or reality. The concept of the uncanny is often explored in literature, art, and pop culture.
