Strong memories can pull you in with great or horrific feelings associated with those moments.
I just pictured an incredibly strong memory of mine when I was about 12. I was playing “rocks” with my cousins at my grandparents place on the path just outside the pool house. Fun and carefree times. It’s like a photograph burned into my mind. Occasionally it’s a short movie.
Strong memories like that feel great and bring a smile to my face.
