I've been reading stories on this site for a while now and I have decided to share mine. First of all I would like to mention that my mother had similar encounters when she was younger, so she did kind of helped me with my experiences.
My first encounter has happened when I was about 13-14 years of age (I'm 20 now). We have just moved to my grandparents' house (village next to Đakovo, Croatia) a few years before that and I have always had that feeling that I was watched.
Kitchen (it's called something like summer kitchen and it is very common in Slavonia) is separated from the rest of our house and you have to cross the yard to get to the house. I was alone in the kitchen listening to the radio and drawing something. It was getting late and I decided to go watch TV then go to sleep cause I had school next morning. I picked my cat up and went across, soon as I have opened the door I could feel something is there standing at my right side watching me. My cat started to make some strange noise and scratching me until I let her go. She ran across so fast, I have never seen her acting that strange. Then I looked to my right and I could see black shadowy like figure of a man staring at me. I couldn't see his face but I could feel it. So I froze for a couple minutes as we were staring at each other. I could feel the cold coming down my back. Somehow I managed to break this paralysis and run across and turn on the lights in my yard and he was gone. I stared though the window for a while trying to figure out what was that or who. That night I could not sleep or relax in any way.
The second encounter has happened few months later. I was in my room again listening to music (I used to sleep with music on) and reading. Only source of light was from my stereo and it was blueish, I have always liked it that way. My father was in living room on computer, my sister was in dorm in Osijek and everybody else were already asleep. It was around midnight and I felt sleepy so I decided to put the book down and go to sleep.
As I closed the book and turned to put it on table there he/it was again. He/it was standing next to my bed once again staring at me. I felt cold, I couldn't move or scream. I could hear him/it breathing. He/it was getting closer and somehow I could move. I stretched my arm and I turned on the nightstand lamp and he/it was gone. I sat on the bed for a few seconds then went to the living room. Since that day I sleep in there.
Next day I have asked my mother about her ghost experiences and how to get rid of them. She told me that I have to set him/it free, just to tell him/it to go. I had that on my mind since then. I have few more encounters but I will share them some other time.
Thank you for your time.
P.S I'm sorry if there are some grammar mistakes. English is my second language.
