My brother and I as well as a friend went to an old spooky 1800s graveyard that always had really weird shit going on,things that happened regularly were when people visit is having several pictures on cameras or phones that they never took even when the devices were left untouched in the car, happened to my mother also.we went out with an evp recorder late at night and set the recorder on an old grave stone at the back and said one thing and walked back to the car and st for a while, we all hatred the idea of people faking evps and noise pollution so we had all made sure not to talk period, after we sat in the car for a while we went and got it then went back to the car and plugged it into the car stereo and blasted the volume to heat anything really good.after you hear us turn the evp recorder on you could hear us all walk away back to the car, about the time we would have reached the car,"keep in mind this is loud in the car and we are parked right close plain sightt of the stone" there was dark most evil voice I ever heard in my life say"shut up" we were all pale white in the face, jaws dropped all the way to the floor looking at each other like this isn't real holy shit! We drove away as fast as we could, still to this day I can't think about it or I lose sleep,I didn't sleep for a week after not did my other friend,I let several other people hear the evp, good friends and family, every single person that heard it agrees that no human could recreate that sound,I got rid of the recorder and deleted every file,I guess you never really realise how dangerous playing with stuff like that is until it happens so clearly there is no other explanation for and I will never do it again, real shit
