Urbex in an abandoned school

So i was walking in front of it but there was no way i can enter it until i saw an open window , so i went home to take my flashlight and my backpack.
I came back at 11pm , it was scary , it took me 5minutes to enter.
After that i went on the 1st floor and i heard some noises of an animal or something so i went back and exit the building.
A day after i came back , and wow the building was huge and there was 2 others buildings behind it who were abandoned.
I took some pictures and video , there was some beautiful graffitis on the wall.
This was amazing.
