Smells

You know when you go somewhere familiar and the smell brings you back to a memory there? Well that's what happened to me. I had to go to the airport to pick someone up the other day and once I walked in, I breathed in the familiar smell of the airport and all of a sudden I got nervous and excited and memories started flooding in. Next time you go somewhere that you've been before, close your eyes, smell the place and see what memories come up.
