This happened to me, when I was seven years old. Here in my country, we have a rich folklore. Mainly, all stories and myths happen to be with encounters with the dead and demons. I didn't believe in these things, until I moved to the green house.
In the beginning, everything was normal, although, I had a bad sense about the house. When I was alone, I felt that someone or something was looking me, but I saw no one. Other common things in this house, was to feel sudden changes in temperature.
I really never minded, until one night. I woke up from a nightmare. I was sweating and I had a lot of thirst so I went to the kitchen to get some water. This house connected all the rooms with one single hallway or corridor. As soon as I got my self out of the room I felt this strange feeling of being seen plus the sudden drop of temperature.
I got really scared and then I fixed my view to the end of the hallway where I saw a dark figure which slowly moves towards me. I was creeped out! I knew this wasn't my sister, because, she was still a baby. I ran as fast as possible to my parent's room.
Days and weeks passed since that night. I started to loose fear of the specter. At this time I began to sleep with my door closed. One night, I woke up from a nightmare. In my dreams I felt as if a rotting body pulled my feet to drag me under the bed. When I woke up I thought I heard the sound of nails scratching my door, in fact the noise was so hard it completely made me wake up. I hid under the covers. After a few minutes the sound stopped, but I was so scared I couldn't sleep for the whole night.
Two months after this last experience, we moved from that house, thanks to those experiences I started to believe and comprehend that the world we see is just very small, out there strange things happen, and there are worlds we can't see.
