Ghost recordings, I wonder what causes everyone to hear the same recording providing it's not altered or messed with.
I know there's already a scientific answer but my question is more like this, see when I went to a cemetery once with a friend, we were just being dumb kids and setting up a recorder just to see what was going on. I do remember when we played it back, we got horse hooves and faint voices in the background, none of us suggested what it was but we all knew it was the sound of animals pretty clearly. This is a cemetery that was farther from town and it was really silent, basically in the middle of nowhere so no distraction.
The reason why I ask is because I was watching a ghost show and they got on a recording faint band music in a jail that was since long gone. Turns out the prisoners used to play music there. I know there's already an explanation but what if everyone hears it all at once?
Even when I was watching it, I said to myself, that sounds like music. And then everyone else in the show was also like "this is music" but way after I already thought it. Sort of like what happened with the horse hooves. Me and my friend just looked at each other and was like, there's no horses around lol.
