"Flash back" is a phrase used to describe a sudden and brief memory or recollection of something that happened in the past. It can happen when you see, hear or smell something that reminds you of a past experience. For example, if you're walking down the street and smell freshly baked bread, it might trigger a flashback to a time when you were in a bakery with your grandma. "Flash back" can also describe a technique used in movies and books where the story goes back in time to show something that happened before. So, when someone says they had a "flashback" it means they remembered something from the past for a short time.
