no doubt on this that Jinn exist in Qatar. One of my friend also suffering from Jinn randomly & he cannot sleep alone in his room now a days. I also didn't beleive about it when my friend told at first. So one day he invite me to stay with just to beleive him. The day we stay together at night was really horrible for me. It was almost 2am someone knock the door & I went out to check but didn't find anybody. I thought it's just happaning inside my mind but after 10/15 minutes again someone start knock the window by this time & no one out there when I go to check. After that no more disturbance & we fall into sleep & suddenly at near about 3:30 I heared sound of my friend asking my help & when I switch on the light I found him in the other room lying on the floor almost naked. When went to touch him he made a scary sound & I went outside of the home call to my other friends over the phone & after half an he became normal. That was really a memorable night in my life.
