DAE completely forget they watched a movie before and then watch it again thinking it's their first time?

So something really weird happened and I want to know if this is normal or if my brain just glitched. In October 2025 I watched Gladiator and it felt completely like a first-time watch. I was invested in the story, didn’t feel like I knew what was coming, and nothing triggered a “I’ve seen this before” feeling. Recently I was scrolling through my phone gallery and found photos/videos from 2023 where I had literally taken pictures of the TV while watching Gladiator. So I KNOW I watched the entire movie back then.The weird part is I have absolutely zero memory of watching it in 2023. No flashbacks, no vague recollection, nothing. The only memory I have is the one from 2025. Has this happened to anyone else? Is it normal for your brain to completely erase the memory of watching a movie like that even if you were paying attention and invested? Or is there some kind of memory phenomenon that explains this?
