Like how the Universe started or what's at the other side of a black hole? Why we have an appendix? Like I say to you, time and time again, when there's two theories/schools, one back up by data, the other by hearsay and hoax, it's not hard to take sides.
I induced a paranormal experience with 3 subwoofers and some recording equipment. Saw a tall black figure which then turned into a more clear reaper figure, the hairs of the back of my neck stood up and I felt very uneasy, the figure stayed there in the corner of my vision but when I turned to face it...nothing.
