Does anyone else have false memories that develop immediately?

Does anyone else’s false memory intrusive thoughts of what could have happened feel very, very real?

When false memories have popped up for you guys, did they feel real straight away like pop up like a memory but you’re still doubting whether they’re real?

Can it feel like you literally remember a false memory happening? And it feels like the memory has always been there and you vividly remember it happening that way? Because I don’t even know if I’m experiencing a false memory or not but god it feels so fucking real. Like I literally remember it happening. But what’s weird is the original memory was kind of different. 2 years later, the memory is not the same, but it feels like I literally remember it happening. And in this memory, I’m fucking snapping. I’m acting on my thoughts. I feel like a fucking psycho. I hope this is just OCD
