I will get right to it. I was living in Serbia, at the time this happened. Important to know that the part of the country I was living in was part of Hungary until the end of the first world war, when it lost 75% of its territory, and these territories were given to surrounding countries. So, there are Hungarians living there. I'm one of them.
It started in somewhere in 2007. I was at church (was Sunday) together with some friends. Everything went as usual, we were bored and wanted to go home so we could play Counter-Strike against each other. When we came out of church the sky was blue, not a cloud on it.
So I arrived home, sat down to the table with my family, said my prayer, ate lunch, and went to my bedroom, turned on the computer, and opened the game selected the server, connected, started playing. About half an hour later (my score was 30 to 5) I felt something touch my neck, spontaneously turned around to see what it was and there was nothing! Now, at this point I was sure that it felt like a cold hand (when it touched me) but there was nothing there! I stopped playing and went to see if someone else was in the house (some stranger), what I found was again nothing. There is no way any one could hide before I would see him/her, because when it touched me I turned around in the same second. But I thought there is some person playing around.
Later that day someone was screaming in a voice that sounded like straight from hell. The screaming went on for 5-8 minutes, none of the neighbors screamed, no animal makes sounds like that and that loud. The whole street heard it, and no one could tell where it was coming from, it went far beyond the limits of what computer software can make.
Ever since, there is an evil presence in that house. I was living there for another five years with my family. The time I spent there was horrific. I was attacked everyday by some unseen force, attacks include but are not limited to: scratches, being pushed against the wall, thrown out of bed, locked out/in, thrown out the door.
I hope whatever it was that harassed you didn't 'cling' onto you when you moved from the house. If these things get attached, they can be very hard to detach. Has the demon followed you?
