What is your earliest memory?

Back when I was 4 I was stuck to the 220 mains because 4 year old me was quite the idiot. My earliest memories were from the months after that where I’d have waking nightmares constantly. Like some AR horror game would suddenly take over and I’d just see this horror scene play out while I was just walking around the house during the day. It wasn’t anything super gruesome, but it was also by no means pleasant.
