This is a story about a real experience that has happened to my friend and I.
Overview: This started some years ago but my friend and I will get the occasional sense that we are being watched by something not from this world.
Detailed story: Some years ago, my friend came to my house for a sleepover. The day he came, we went and did something outside to keep us occupied - My parents and brother went out for a little while in town.
My friend and I eventually found a way to get bored so we went inside to play a game on the Wii - It was very popular at that time.
When we had finished a round of tennis on the Wii, we both went to get a drink and something to eat. After we finished, we went back to the Wii and had another round, In-game, I mentioned to him that I felt as though something is watching us from the couch (my brother and parents were still out in town). He said he felt the same feeling when we were outside but didn't mention it because he'd thought that I would think he was stupid.
I told him that maybe we should stop playing and do something outside because at least then we would have somewhere to run if something extremely bad were to happen. As we got to the front door, we both stopped and realised that whatever was watching us was right in front of us. We immediately turned back and quickly went to the back door, hoping to get out before the "thing" got there before us. We got out and ran to the front of the house and discussed a plan.
We didn't get far into discussing before we both felt a presence of something standing next to us. We both knew that it was the "thing" that had watched us and blocked us off previously. We started running again and stopped at the gate to catch our breath (I live in the country and my drive-way is long). We waited to see if the "thing" had followed us.
The "thing" had not followed us so we decided to start slowly heading back to the house. My parents and brother came home and stopped next to us and asked why we were down there. We told them why but as usual, they didn't believe us and told us to get into the car. We got home and my friend and I could not sense the "thing's" presence anymore so we both thought it had left us alone.
My friend and I have not had anymore experiences like this since that day but we do still get the occasional sensation of being watched, only watched.
