Only time I’ve had something like this can be easily explained by a prank but it just doesn’t seem like it was.

Worked on a site that had fire damage, old student accommodation that was being demolished but needed to have all the gas appliances decommissioned and removed. The site had a security guard and the plot of land was fenced off unless security gave you access. Me and the 2 other lads I was working with were in the room with the worst fire damage, black soot up what was left of the walls, windows shattered etc.

We were just talking, when a shrill scream echoed through all the corridors. All of the hairs on my body stood on end, the three of us must’ve had the same feeling because we all ran out of that building quick as fuck and didn’t go back in. Luckily our work was done in that particular building.

I would’ve said it was probably the security guy having us on because we got along with him while we were there but I just don’t see how a guy with his voice and stature could’ve made such a loud high pitched noise, it sounded distant at first but carried as if someone was screaming in the same room as us.
