Memories keep popping up, but as you say they only come in short pictures.
As I read your post, my brain has started a posses and looking back in time.
What comes up is when I am approx. 4-5 years old is a picture of me getting angry at something and cracking my shoes off and throwing them off. I run on a road that has asphalt and manages to scrape up the toe while I run and start to bleed.
And there it stops with the picture that came up
I would think I was angry about something I was not allowed to do by my parents, or maybe I was not given an ice cream 😊
