i have had a couple experiences, i know when something is near. its hard to convince skeptics haha, but this one time my buddy(an atheist) came over to my friends house(i lived there two)... me and the atheist were outside, and at some point i got the feeling and muttered "no, it cant be". next thing you know i'm inside my friends house watching this evil entity walk in through the my room, i observed it as it walked towards the kitchen door i was next to. but then i hear my atheist friend yelling my name distantly, then i awoke from a trance and he was violently shaking me and screaming my name pointing at the house. so i look at the house thru the kitchen window and i could see the ghost/entity thing, it was standing in my friends body(possession?)... it turned and looked at us and then left. we ran inside and my friends said they didn't see anything but they had felt some immense fear, the kinda fear that makes you pale and your knees weak.
my friend almost shit his pants i've never seen someone so panicked. the ghost was a teenage Asian girl from the 1800's, she had a white dress that went down to her knees. here's the kicker, we've come to learn that the land behind my buddies house has an old Asian couple living on it, its been in their family since rail-road times. my room was also the closest to the Asian's property. the atheist decided to re examine his views, hes not religious just agnostic for now lol, at least he will acknowledge and listen to my banter now
