Okay I'll you more. I'll come to the Jinn part later. First, let me tell you what happened with me.
It was in my home country, somewhere in south east Asia. I used to go to the rooftop of my apartment quite often to see the sunset. One day I was looking toward the sky. it was twilight time. I was standing near the edge. Suddenly something hit in the back of my head. It was like something punching right at the back side of my head with a closed fist. It was a sudden and quick blow. I quickly looked up and looked around. The rooftop was empty. The first thing that crossed my mind was it must have been a bat flying low. Bats and one other specific type of bird flying from twilight to night time is common in that area. However, I could not see any kinds of birds nearby, neither I had heard any "wheesh" sound from any bird's wings. That's when I began to feel the fear.
A few days later I began to ask some people about this who had lived in that apartment for long enough and discovered that almost all of them had the same experience once or twice. It happens only when you stand or sit in a specific territory of the roof. It almost never happens in the day time. Starts happening from the twilight time ( by the way, twilight was pretty clear, I could see everything). It happened to me a couple of time after that. I have also witnessed one of my friends getting hit by this mysterious thing. He was standing near the edge in the evening and I suddenly saw him to kinda make a ducking movement. When I asked him what happened, he said something hit hard at the back of his head. I had stopped going to the rooftop after that. Soon after I left the place.
Now, about the Jinns. They are some supernatural creatures described in the Quran (
Wikipedia ) (well, the concept might be older than 1500 years but I got know about it from the Quran). So as a Muslim I already knew about the concept. They can see you but you can't see them. So I figured it could have been a Jinn for all I knew.
By the way, the blow was quite hard. It still remember how it felt. So, I 100% believe in the supernatural creatures.
