Just wondering if anyone has any solid evidence of physical harm/movement from Demonic or spiritual life forms? Pictures of wounds? Videos of objects moving untouched? Documented reports that are even semi-believable?

Personal accounts are welcome.

I've heard stories from my family about poltergeists, possessions, demons harming family, and angry spirits bent on revenge... but they are not really my personal accounts to share.

Blah.

I've heard of various cases of poltergeist activity, but most of those turn out to be manifestations of telekinesis from someone still alive.

Hmm. Well, first of all, Poltergeists are nothing but energy surrounding a person or object. Not neccessarily a ghost or entity. The movie only got it half right. As far as proof, I don't have any personaly. Anything that has happend to me or my family I can't really prep for any of it. It just happens. It's only by sheer luck it's ever caught.
Demon attacks, I can honestly say I've dreamnt of being attacked. But it felt so real. I was lying in bed and my whole body became stiff. I felt my eyes roll to the back of my head, and heard a deep voice. I couldn't understand what was being said. Then I woke up, and slept in the livingroom. It freaked me out so much.

Im going to be honest there are such things as mean ass ghouls and ghost...most of the time they dont want to harm us but there are those that love to cause harm. i have two personal experience:
I was walking by my father's room when i got this feeling that something evil was in there and the next thing i knew is that something was hissing at me..so i just walked away brushing it off my shoulder..well the next thing i did was i closed my father's door and i heard the same noise again. then i went to bed and i heard papers being throwen around and the bed was moving and all these other crashes and bangs. so my older sister came into my room and we were going to sleep together cuz we were so scared. then she had a light breeze go up her arm and i heard something crawl up my wall so we slept in the car that night. and the next dad when my father had gotten home he had asked us who had slept in his bed because there were impressions of a person's body on this bed

another example:
i was playing the ps2 in my dad's room and i accently fell asleep in his room and bout a couple hours later i heard someone say get out to me. at that time i thought that it was just me hearing things so i rolled over and went back to sleep. then next thing i knew was i flew across the room and hit my mother's dresser and then i locked myself into my room and didnt sleep after that.

so to answer your question there are spirits that can harm us and that might wish us harm..
i hoped i helped in some way

Don't know if this counts but once over a CD a voice spoke it said "Ive been here since November" but this was not there upon rewind.

It was so spooky because a lot had happened in the past year i just wish i would have had proof but who records everyday things.
