Other commenters are trying to gaslight you into believing this isn't possible, but I also have a memory from before I could walk.
I was lying on the floor, contemplating a toy that had been hung above my head, when someone who was not one of my parents came to pick me up.
Years later, I told my mother about this. She then searched through the family film archive, and found the moment in question. The person who picked me up was my uncle.
This was not a film we had watched before, it came about because I was discussing with my mother our earliest memories.
You have one memory of all the time before you could walk, and it just so happens to have been caught on film? You don't find that suspicious?
No I do not. Years of my early life are on film. My parents were enamored with their camera, it was frequently set up to film the entire room, passively.
When I say my mother searched for the moment, I mean she searched through tapes that had never been viewed from her archives.
I normally try to live my life in the spirit of XKCD 386, but I leave this response for the sake of clarification, to not discourage any future readers.
Seems farfetched to believe that you happened to have the exact moment you discuss on video
Haha yeah, I am used to the skepticism.. I've thought about this a lot. There are so many things I've confirmed that aren't in photographs or stories I've been told that it seems to be real.
I also have aphantasia, I have wondered if my lack of visualization has somehow empowered my long-term memory. I rely on memory for "visualizing" things.
