What cause is this?
Most people have much more 'perceptual' ability than they are aware of and much more than they use in everyday life. These are through the combination of the standard five senses and nothing to do with special powers.
Some people are more adept naturally this or you can train yourself to be more intuitive, read body language, facial expressions, understand non-verbal communication etc.
I don't believe in a 'sixth sense' as seen on TV.
