I don´t remember well, but I read one magazine, and scientifics says that our brain works quickly when we are walking and seeing around us, and all the images our senses capture our brain process them and that´s why we feel we knew about a situation before it happens.
Mind is a powerful tool, but I don´t think in people who thinks they can see the future readind a ball of crystal, the hands or something like that.
we are living in the word surrounded by one information field , some people are more open to read this information , sure it helps us to predict future events . sombody call it intuition . for instance it helps us to explain why mother always feel if her child is in danger or how you can feel mood of the person you love even if it's great distance between bouth . but who form that information field , which is so powerful.. sure we do , all our thoughts and deeds. so in that case we can predict our future. thought comes first :)
