I never looked into anything like this, but is the odd ability to know the unknown at times, "paranormal"?
For example, when we are sitting here and for no reason one was to tell his wife what the daily pick 3 numbers will be and they come in right then? Or when someone turns to his wife and says "XYZ" is going to call and it happens. If I was to try and do anything on purpose, I couldn't. But when it just pops into my head, its almost always right.
Freaks my wife out to the point that I don't say what I "think" is going to happen anymore, but she often catches a look on my face and ask's if I knew that was going to happen. I must be a superhero and now realize it.
