To get a good view of the scientific perspective of the kind of thing you're talking about, we need to consider your brain.While some people like to compare the brain to a computer, there is at least one major way in which it is completely different. As most of us have probably noticed at one time or another, at any given moment a computer can only be carrying out ONE task. It might switch between many tasks quickly and SEEM to do many at once, but if you run across something big that chews up a lot of processing power, you will quickly discover that until your computer is done everything else is pretty much at a standstill.This is NOT the way your brain works. Your brain has millions of neurons and they can ALL work more or less independantly. Though your conscious mind may only be thinking about one thing at a time (like a computer), all the other parts of your brain are humming along and doing their own things AT THE SAME TIME. Your senses still collect and process information, your memory is constantly bringing up correlations, and your body is still kept functioning - and many other things are going on - whether you pay attention or not.This can create interesting situations. Because non-conscious parts of your brain are still 'thinking' in a way that is outside your awareness, you can actually know things that you don't KNOW that you know. Most of us are familiar with this in a variety of ways. Like when you stop thinking about a difficult problem and the answer just 'comes' to you - you WERE still thinking about it... just not consciously. Or when you get a 'feeling' about a person or a situation that turns out later to be true - you may have collected very subtle sensory and memory information to create that impression.Just be careful not to give these other parts of your brain too much credit. Though they may often notice things you otherwise do not, they are not really any more accurate than your concious mind. And sometimes much LESS accurate. This is often the source of an irrational fear that psychologists call a phobia - your unconscious mind has associated a harmless thing with a bad or dangerous thing and makes you feel fear where there is no good reason.It is the nature of the human mind to notice the unusual. So even if you perceive that these impressions are almost always correct, it may just be that you are noticing a statistical anomaly. One way to prove it to yourself is to write down EVERY impression you get, and check back later to see which ones are right and which ones are wrong. I have little doubt that you'll find your unconscious isn't much more accurate than your conscious is!Hope that helps!
