This happened in a small town in italy, many years ago. Friend was staying with his parents in a small village. Him and a few of his friends decide to do a weegie board in a local abandoned church. (nothing good can come of this if you ask me)
Anyway, a while after messing with the weegie board they saw a black figure floating in a dark cloak and the crucifix of jesus had tears of blood on it...
They ran from the church and as they were walking home they saw a small gargoyle type creature sitting on the branch of a tree talking to itself... at that point they legged it.
Granted he must have been about 16 at the time (29 now) but I think to myself why would he lie...
Another one is when I was young, my parents come from a small village in portugal. My dad told me his saw a young girl possessed and she managed to knock down a tree...
They called a priest to perform a exorcism of some sort. During the exorcism my dad described it as 'like her skin was being pulled from her body'
Again, why would my dad lie? he has nothing to gain, he's like 58 now..
Anyway, believe or not this is how it was told to me.
