I remember this creepy thing still very strongly, because this was one of my scariest moment of my life. I remember I was about only 3-4 years old and I still remember this that bad.
I asked for my mom and she said that I didn't never woke up in middle of the night for no reason when I was a kid, but that night I did.
I didn't seen any kind of horror movies or anything like that at the same time as this happened, so it wasn't just some imagination like my mom and everybody else said.
So I woke up in the middle of the night, I don't know why. The same time as I opened my eyes my door was open and I saw a very tall black demon with devil's horns standing on my door. It really had those very creepy red eyes and it just stood here and waved at me with right arm very slowly and creepy. It was so dark but I saw red eyes very well and it had pretty long "nails". So I was so young I thought it was just some "monster" who tried to scare me, so I pretend I wasn't scared and I just said very quietly "hi monster..." and I was shaking and freaked out. I slowly turned my body away from the devil to the wall and start screaming mommy and crying.
When I screamed about 5 seconds, I look at the door where the demon was, I just saw it faded away very slowly... I don't remember anything what happened to next, I think my mom came to my room or something like that. And I told about the "monster" to everyone, no one believed me. Now when I'm older, I'm sure it was a demon. Still this really scares me out.
