Why do Ghosts haunt the land of the Living?

When the manner of Supernatural Forces or Beings is brought up in a conversation, this is usually the very first question that comes to mind.

....why?

Why do Ghosts spend their time here among the alive people? There's been multiple interpretations as to how something like this could occur, based on different events and experiences. Most pausible one was the study of therapist Victor Evans on the manner of the "Un-Dead", as he calls them.

Mr. Evans was witness of communication with "outside forces", an alien, he first thought, upon further communication Victor realized he was talking with a real person due to the way said being would communicate.

"I'm a therapist, my work revolves around real facts, studies of the human mind and how it works and responds to specific stimulus. However, once i stepped into the room, 3 men and one large radio device, I experienced what I believe to be real Human-Ghost communication. I came to realize I was talking to a human being once I started 'communicating' with the force speaking via the Radio, none other than an old patient of mine who passed away years ago, it couldn't be any cheap trick or anything akin to that, I would know.

After experimenting further with this Radio device, trying to properly communicate with beings from outside the living, I started noticing a pattern. All the voices from the other side of the machine wanted to 'tell' me something, it's always something they have to do before it cuts to that chilling static noise that would sound once the communication had ended. Unfinished business, as they call it. Names, events, all sorts of stuff they need to get done before transcending to 'the place'.

It wasn't any sort of stuff like 'purgatory' or anything remotely similar to that, they'd reffer to the place they're allegedly trapped in as 'a lobby' of sorts, which could explain the music that would constantly play as we tried to gain information on what these voices are.

Once i started writting about this, the voices stopped. They may not like being 'watched'. After a few weeks, this radio became completely obsolete, it couldn't play music or tell me the news. It was all just..... static. Though I could swear I've heard whispering from time to time on this machine.

Whatever this was, i believe it could prove the existence of a greater plane than we initially thought, one that can barely grasp on the physical world, but can easily tamper with the psychological. Fascinating."
