What is the most horror or eerie thing that has happened to your (asking in horror context)?

When I was young, me and my friends, we went into some spooky uninhabited house in the city just for fun.

It was a sunny day and suddenly when we went inside, strong thunder came out of nowhere and we all got so scared by it 😀

We were kids so that’s why we got scared, not sure if I would be scared by this now.
