Sometimes we feel anxious..and yet we donot know the reason for it..It is,as if ,waiting for something to happen..waiting and waiting..in anticipation of an event to occur..which has not happened..and because we are anxious..we are also restless..and we also do not know if we are waiting for something good to happen or something bad..
I have heard about people who can feel or predict(?)if something is going to take place in near future..though I have not come across such people..and here I am not talking about soothsayers..but, ordinary people..just like you and me..who can sense if something is going to happen...they are the people having extraordinary sixth sense..and this brings to mind the thought provoking and chillingly real movie of M.Night Shyamalan.."The Sixth Sense".
Some people call it "telepathy"..we do feel sad if something goes wrong with our near and dear ones..when they are away and we have no actual knowledge about their woes..May be ,it happens because we are emotionally too close..and our extra sensory perception feels about them..
There is probably no scientific theory corroborating this as a fact,but can everything be explained as facts only..there are still a lot many things that cannot be explained scientifically ..but,they are there all the same...Science does not acknowledge the existence of GOD..but donot we believe in HIM?
