I call it my 'stoner sense,' and its almost the exact same thing. it works better when im high though. the fact is, the chemistry of the high is an increased rate at which various brain chemicals are processed, sometimes giving the person under the influence a 'slow' or 'timeless' feeling. like Data on star trek. in that case, its possible that such action have the capacity to increase the capacity of the brain in certain people. I, personally, don't believe in the ability of the brain to communicate or sense things beyond what its been proven to be progammed to, but it is possible that your mind is moving a lot faster without your knowledge as a result of frequent stimulation. in such a case, you could subconciously interpret how a person talks aor acts so well that you could, in effect, predict their next action to a dgree of certainty. that, or you were bitten by a radioactive spider.
