I believe everyone of us gets occasional glimpses of "insight" under certain conditions or circumstances. We all have said, "Something told me.....etc"
We have also experienced driving along a road and we've looked in the rear view mirror to see a car approaching at a high rate of speed in the lane next to us. Based upon the fact there is a truck up ahead in that lane we suspect the driver of the car plans to race up the truck and cut over into our lane.
Now if you were testifying in a court of law an attorney would tear you apart on the witness stand by asking you such questions as "Could you read that driver's mind?" "Since there was no light signal change indicated....Can you with 100% accuracy state this driver intended to cut you off? Is it possible the driver was planning to slow down once he caught up to the truck?
When it is all said and done our (feeling) combined with our experience often tells us "something is not right". However we have been so conditioned not to trust our instincts but rather allow things to unfold. I believe those who learn not to question their "inner guide" tend to be what we call "psychic" or having ESP.
