See unfortunately there are so many things out there that are unexplained, and yes I have had my own encounters with some freaky shit, I have seen shadow demons and other shit, at first I thought it was bullshit till I did some research right to the point where my apartment USE to be a cemetery that they dug up all the bodies and moved them to build an apartment complex after dealing with all the bullshit and even my roommates getting scared as hell from the shit we saw we all moved the fuck out. I could see someone with a weak mind getting possessed without a doubt.
