I had an interesting experience in an abandoned residential school I broke into with my friends when I was a teenager. The first time I went, we broke down the barricades nailed over the windows, and once inside found it to be full of old classroom stuff. There were tons of spooky moments we all collectively shared from that night (feeling like someone was watching us from different class rooms, a dense and fearful energy in the cages found in the basement, a super ominous feeling in the small crawlspace, and voices heard in hallways etc) I decided to return with my friends after about 6 times, but the second time around it would seem far more people broke in, a lot more barriers were torn down, a lot of classroom items taken. that second time none of the intense energies seemed to be there,.almost like the place hollowed out I'm not sure obviously if it was just Me less scared of the place coming back the second time, but I do feel like I have some extra sensory perception, and it was honestly really interesting to feel the difference in vibes, almost like when more people entered and took more stuff, the energies left through the open windows and broken down doors along with them.
