intrusive thoughts and false memories

Is a false memory a type of intrusive thought?

im going to be vague here, but basically i did something in the past that i regret and it became a huge point of my OCD but i have talked to my therapist and i have mostly moved past it. i watched a video by an OCD youtuber that really put it into perspective. anyway, i have been with minimal worry for a few days, but now im having worries related to i think false memory? basically it’s like “oh but what if i said/ did this and just forgot that means i harmed this person im a bad person”. to me it sounds like textbook OCD but im just wondering if anyone else has experienced false memory / real event at the same time. i have a really horrible memory which is making it even more stressful. any responses are appreciated!

I know I was here earlier on with a question as well lol but has anyone ever found that when a new false memory takes its place at the forefront of your mind, it's almost easier to disregard the old false memories and say "Yeah that stuff didn't actually happen that way". It feels like OCD giving you a little reward for letting it place a new, shinier false memory in your head. Anyone experience the same thing? Maybe I've asked a similar question before.
