Step one for seeing any such phenomena claimed to be of paranormal origin- be a true believer before you get there. The people who swear this stuff is unexplained or otherwise paranormal are always people who want it to be. They’re also always people who believe in all the other stuff- Bigfoot, ghosts, alien abductions, whatever. No rational explanation will ever convince them and if you go into these events with a rational outlook, you won’t see what they see. I knew someone who firmly believed their apartment was haunted because of noises that were clearly people in the adjacent stairwell going up and down.
Some people need the fantasy in their lives, I guess?
