I Am Interested In the Paranormal

I once heard a story about a hospital in the US where thousands of people had died from tuberculosis in late 19th century. They stuffed the bodies in the so-called Death Tunnel. I don't know the name of the place but it seems to be one of the most haunted places in the US. I hear people wanting to go there for the creepy vibe or to capture some ghosts on camera, but all I want is to help those poor souls trapped inside those walls. Sadly, I have no idea where to start- from paranormal investigators I've heard that the spirits there arent malevolent but miserable and sometimes confused, so I'm sure a peptalk wouldn't help them feel better...
