In my experience with ghosts and weird stuff, I thought about these theory or crazy idea that spirits, ghosts, etc have some sort of ground to walk on.
In my home where we always change the position of our furniture and other stuff, I noticed that there are some ghost only appear in a specific order or positioning of our furniture.
We know that some ghost can just pass through things and the living, but what I experience through time is that I can prevent some ghost form re-appearing simply by changing the position of the things in a room.
My theory is that some ghost have a specific pathway like a spiritual ground/field. Its like there is a specific flow of energy in a room where you can block their pathway so that some spirit or ghost can't get through.
I am always having these weird sleep paralysis where I always see a ghost always holding my foot and saw some sort of tunnel beside me. Call me crazy but somehow I did according to the theory that I thought about and it was quite helpful since the frequency of my sleep paralysis drop.
Is it just me or i dunno if you guys tried this before?
