The missing years

I just remembered something that I think might have happened in the years between the age of 3 and 6. I generally don't remember anything from that time period and only have a some memories that I can't really place in time that I thought might have happened then, but might also have happened later.



I'm also not sure how to judge this. How not normal is this on a scale from 'yeah, I guess a bit out of the ordinary' to completely unnusual.
I'm not in a very emotional state over this, btw. Not sure what to do with this, really.

Any thoughts?

That sounds a bit odd?? I think the most concerning parts are if they ever used a real knife and if the "play" truly did include any sexual components. I think it also matters how much older than you they were. A group of 3 five year olds might not know any better, but it gets a bit weirder if there's more of an age gap.
Since it isn't currently causing you any distress I wouldn't worry too much about it. But if you start to remember more or the memories start to concern you, then you can always try to talk to a therapist about it.

My cousin is the same age as I and my sibling is a little more than 1 year older than the 2 of us. I don't want to push the memory at the moment, so I am letting it rest
