why does our brain play tricks on us? Shouldn’t it “protect us” by not scaring us?

I”ve posted this in another sub too but thought maybe I get a more detailed info about our brain here.

Basically I read on the good old internet that if you stare for a period of time into the mirror that your brain will start playing tricks on you and scare you. Well I wanted to see for myself, indeed it did happen. A few times I thought I’ve seen someone behind me for a split second, or that my face moves even tho I didn’t move a muscle etc. Why would our brain do that to ourselves since it could harm us by making us panic therefore it being bad for our brain? Is there any reason that our brain does that? I’m quiet certain it’s not to protect us is it?

Additionally does this maybe explain why people say they seen bloody marry or other ghost storys connected to mirrors? That our brain for some reason plays tricks on us? Since if we go into the bathroom and we expect to see bloody marry by doing that ritual that our brain tricks us and makes us see it just cause we expected it to be there?
Maybe Im thinking too far

Why does our brain do this? Shouldn’t it do the opposite and protect us from it?

your brain is a time machine. it tries to predict what will happen in the future so it can protect you from danger that hinders your survival.

that machine is optimized for scenarios where real danger is present (cause it really can make a difference to your survival). While false scare to no danger doesn’t really impact your survival.
