The Truth About Why Your Brain Feels Like You've Been Here Before

Déjà vu is an illusion, not a memory. Learn why your brain creates this strange sensation of reliving a past experience. This breakdown explains the phenomenon of déjà vu by exploring how your brain attempts to recall a source for a familiar feeling. We examine the neurological confusion that occurs when your mind misinterprets current sensory input as a past event. By looking at the biological mechanisms behind this glitch, we clarify that the experience is a trick of perception rather than evidence of parallel universes or simulation theories. We also explore the limits of human memory and why your cognitive processes sometimes misfire when trying to categorize new information. This video is for anyone curious about the mechanics of the human brain and the complex interplay between sensory input and memory formation.
