Let me share my experience in my National Service Camp encounter.
Well I am a chinese, and chinese mediums (a friend of mine in camp too thank god) can somehow count what happens (supernatural activities).
So I asked him that night (as there are quite a few girls kena ady a few days before) and he say "Weird, today is a guy." So I said that "whoever guy that kena really sui"
Proves that I'm correct. So as I walk to the hall (it was a padang kawat and surrounded by oil palm estates (yes it's f***ing creepy)) and half way through the field I can sense a very fast object flying zigzag from my back (I am sensitive)
For those who watch bleach, it's the exact feeling of a different reiatsu (spiritual level) like Ichigo meeting Zaraki Kenpachi for the first time. Exact same feeling, no kidding. That freaked me out.
The next moment I found myself floating where I cannot move my body. That dirty thing knocked me out of my body apparently. So I felt dizzy for a while and faster yell at my friend "eh come I kena dirty stuffs".
Well after awhile I regained my consciousness and everything's alright again.

It's up to you to believe it or not.
