Spooky encounters? - Thread - Urban Exploration Resource

Not really a big believer in paranormal type things but I've had some interesting things happen, or rather my brother has and I've been there for one of them. Him and I and his girlfriend were in the very well-known TB hospital in NYC. I am 99% sure we were the only people there but I suppose I could be wrong. For most of the time we were there, we had split up and I was alone taking pictures while he and his girlfriend walked through the building. I was shooting with a large format camera that day so it took a decent amount of time for each picture I took - so lots of standing still, working in the same spot, and not making much noise at all. While he was on one of the floors above me he started messing with his girlfriend, who was already scared enough, by recording some EVPs and "taunting" the spirits of the children that died there. He heard nothing while doing the recording, and neither did I from where I was right below him, but I got a call from him later that night. Apparently he was laying in bed and finally got around to listening to his recordings. In one of them, after asking some dumb question, there's a very clear high-pitched voice that sounds like it's coming from down a hallway yelling "Hey, come back!". He apparently jumped out of bed when he heard it and I gotta say, not believing in any of that stuff myself, I still can't really explain it.

He also had another experience a few years before that exploring some drains on Staten Island with a few of his friends. They got pretty far in before coming to a split in the drain, with one way leading to a dead end with a bunch of garbage piled up down there, and another way that seemed to lead on further. They all shined their flashlights down the way towards the dead and and saw nothing but the garbage, then down the other way, and then back to the dead end again where suddenly what looked like a little girl in a dirty dress was standing there staring back at them. They all saw it, all froze, until someone managed to say "Time to go" and they all took off. I wasn't there, so I can't vouch for that one, but I have no reason not to believe him.
