One of the scariest moments of my entire life

It was a Saturday I was hanging out with my friend. I live in a pretty small town. There’s not much to so we decided to explore this high school that got abandoned, only 4 years ago at the time, we never explored anything so we didn’t know what to expect or what to do but we took a back exit inside we had to hop a fence to get in then we used a broken window to our advantage to open from the outside. as we get in we see spray paint on the wall and the air was heavy after about 30 minutes of exploring we start to goof off more and we hear something slam against the floor all the way across the building *three story building* and then we hear a gut wrenching scream so me and him were freaking out we ran away from the scream to a nearby exit but then after we leave my friend says and I quote ”we should go back in it may be *insert name*” we both knew this person and he goes in there all the time so we decide to go back in after looking for him we see a group of friends we hear one say ”oh shit its the cops“ and then my friend yells “it’s me *name*“ we see one of the kids pull out BEAR MACE on us we didn’t get sprayed but he almost did but then we all calm down and a person from the other group has the bright idea to play hide and seek so of course as teens we do that and then we hear ”THE COPS ARE IN THE BASEMENT GET OUT!” so we run across the entire school finding an exit and we do then we run to the McDonalds of all places across the street And It has been a year since that incident and I still get a little bit stressed thinking about it To this day.
