When I was younger sometimes I would think I was crazy. I had this strange hypothesis that the life I lived was only perceived by me.
Something would happen and I would think like "what if it's just me who saw that, who lived that and everyone else sees me react to what I thought is what happened and think I'm crazy" which I see now has a lot of anxiety implied, but also I would think some other times like "what if it's just me who saw that, who lived that and everyone else lived something else entirely or lived what I just lived but another version of it".
Like everyone was living in like their own bubble shaped by their thoughts and their "craziness".
Later then I found out about philosophys like Taoism, non-dualism, law of assumption and so on.
I was not crazy, I was actually very close to what I think it's the truth. We all shape our own realities through our beliefs.
Also talking about perception there's a lot more to add to this that 12 year old me would've go crazy for, but that's for another WAY LONGER post. I'll upload it in a few days I think.
As a final note I think this is why like sometimes we'd think certain manifestations are not being made. Someone might be living them in "their" reality, but since we "only live in ours" , and our beliefs are that certain things don't happen or whatever, we do not see these things happening.
Tho be mindful; things like "their" and "our" reality are like practical or rather explicative concepts more than actual things, at least for me.
