Yeah. My earliest one's go back to about 5 or 6yo. A lot are vague memories like sorta kinda remembering what a building looks like, but some of those might be partially based having seen videos and having stories told and inventing memories to match. But some involve me remembering my own thoughts, like remembering being sorta jealous that one of my kindergarten friends was playing with another person or feeling like a couple of my closest friends (both girls) in 2nd grade didn't really see me as a boy, which are things I would have told no one.
