It is a psychic ability. Just remember if you had any difficult affair with a girl or lady. You must have lost it after that. Hinduism prescribes meditation coupled with Yoga to gain psychic abilities.

Hey VSPrassad, well, yes i had that,thank you very much for your answer!, do you think any kind of meditation will work? Regards.

Please don't take offense to this answer, because I am just sharing my own experience here. One time I used an drug called Ketamine (Special K) which can distort your sense of time and reality. While I was under the influence I had the same feeling- every time someone would say something I felt amazed that I knew what they had been about to say. It was a feeling that I was able to see what people were going to do just seconds or minutes before they did it. When I sobered up I could obviously no longer do this, so I sat down and really tried to think about it. Special K distorted my sense of time and caused strange delays between my brain and motor skills. After careful review I realized that what I had been experiencing was that distortion. I was never able to say what people were about say until after it occured. I was simply left with the feeling that I HAD known. Now, I am not saying you have been using drugs. I am just speculating that it is possible that this physiological or psychological effect could be at the root of what you are feeling. How far in advance did you actually see what they were going to say? Were you ever able to to tell them what they were going to say? Did you test it in a way such as writing the phrase down and then verifying that it was what they were going to say? I don't mean to down play your experience, but it is only through careful self examination that we can understand things like this.
