Because psychic abilities do not function that way. It is not a controlled thing, like say, making a sandwich...It comes as it comes, in bits and pieces, in a flash, in a dream, in symbols and in many other ways and is often cryptic and hard to interpret precisely...It isn't like a compass...it is more like an impression...
So if you do not think they exist why are you reading the thread that ASKS for psychic impressions? There are plenty of other "concrete" threads for anyone who does not believe...in my own opinion...
