ShadowMan- Someone Is Watching You Always!!!

When you walk or sit somewhere you feels that someone is behind you watching you always. Is there really a shadow man who is watching you?....

sometimes when you are doing some work. At a time you get a feeling that someone is watching me. But when you look around there will be no one. Is there any shadow man who is watching you. May be there is someone who is watching you. Or be may some subconscious sensation in our brain.

Our subconscious sensation of our brain is so powerful. Even though we don't see someone, it doesn't mean that our subconscious brain is not noticing something in our peripheral vision. any air movement, breathing, vibrations, any sound... any one of these can account for it. And, of course, it does not happen all the time. It is not infallible. 

There is something called Availability Heuristic, which tells that  our memory keeps track mostly of the interesting events, so when you feel something amazing  like sensing the staring of someone, we would remember it over another 100 times when we didn't.

May be we can say it is due to  "Sensed-Presence Effect" in our brain- where our brain produces the sense of someone present when no one is there.
