If something can harm or expose itself to you in "reality" that implies that it has a real body, vocal abilities and more. This would then be a measurable event by even something as basic as a cell phone camera. Since more and more technology is getting into the hands of people everyday its not long before someone films one right? I mean a real good clear obvious recorded event. Where does this demon get his food? Does it sleep? Did it speak english? Did it have an 8th grade education from a US public school?
I am not trying to be "smart" but these are all points that directly effect reality. For a "ghost" to be able to push something, speak or show it self it would require a real body and real parts, namely a brain.
This is some of the things we experienced.
1) A strong unwavering sense of being watched from a specific location.
a) At night I was able to sense being watched from a specif point in my room.
b) One of my daughters came to me and told me she felt being watched everytime she removed her clothing. I questioned her and told her not to mention this to anyone.
c) I waited till the whole family was together and simply asked if anyone had felt being watched. My son said yes and identified the same exact location within a foot of where I felt it.
2) We saw apparitions
a) My son also described seeing our dog Kona, a rotwieler, who we had put down months ago.
b) My son also described being touched by a dark ghost on his arm which caused a numbing sensation.
c) I saw a dark shape , what I assumed to be my oldest son walk into my bedroom and walk into the master bathroom. I was on the computer at the time and realized he made no sound as he walked. I immediatly went to the master bathroom and no one was there.
3) Other things we experienced.
a) My wife laid down in my daughter's bed who had recently moved out. My wife then described a strong sense of my daughter being in the room with her.
b) I experienced strange dreams of a dark smoky man shape.
c) I heard a goat like voice say the name "Baphomet, Baphomet, Baphomet".
I experienced more but at this point no longer feel it wise to go on. You can make whatever deductions about this but I know what all happened. I was there. I can't prove any of it besides my family saying the same things or similar things.
