Why Do Memories Feel Like Flashbacks?

Have you ever smelled a cookie and suddenly felt like you were five years old again? That is flashback memory at work. It feels like time travel because your brain plays the memory in high definition.

Usually, our memories are just stories we tell ourselves. They are fuzzy and flat. But sometimes, a sensory trigger like a song or a smell wakes them up fully. Your brain switches from telling you about the past to showing it to you right now.

This happens in the part of your brain that helps with maps and locations. When this area lights up, it reconstructs the scene around you as if you were standing there again. You do not just remember the fact; you relive the moment.
