aphantasia and hyperphantasia

I've never been able to imagine stuff in my brain such as an apple, i see blackness, a void but i see very distinct shapes at the same time that aren't even related to what i think about but at the same time i have 'memories' of stuff i've heard that's happened to me but i have no recollection of it ever happening, it's like my brain took a video of something happening yet i don't feel like it ever happened because i've only been told it, i got told whenever i was 2/3 my uncle wrangled a snake in his backyard because it was next to me and i didn't know this happened because i was so young but my mind created a 'video' of it happening and it's as clear was watching a youtube video but i know that isn't what happened because i don't remember it and i'm just very confused on what's going with my brain because i have such detailed thoughts and see such detailed things but whenever it comes to trying to imagine something i can't and i only see a void
