You know that feeling when your have your back to something, and you feel like you are being watched? Probably because you are. The voices you think you hear are real. The shadows you pass off as imagination are real. You need to open your mind a bit, it's a natural instinct to know when someone is watching you. For instance, in class, when you feel as if you are being watched, and you look up... And someone is looking at you? Ya that, that's what I am talking about.
Some say this instinct is slowly decreasing through humanity. Humans do not need to use this instinct anymore, or so we think. There are to many things that we are unaware of. Such as ghosts and spirits, those too are real. Don't feel fear now, they will only come out and show themselves to you when you don't believe. If you believe, you are safe, from me, but for now I am looking at you... always watching.
