New York Psychic  

You didn't use any physical senses(See,Hear,Touch).

Yet you felt compelled to turn around. It happens to everyone you speak to, and my answer is very simple. While standing there you tapped into your Psychic senses and picked up either their stare or even sometimes-bad intentions. My next and last example event that’s happens that everyone experiences. How many times have you thought of someone and haven't seen him or her in years and all of a sudden they either call you of just show up out of nowhere? Mathematically if you haven't seen or heard from the person there is a high chance that it will remain the same. Then, this fleeting thought comes to you and (boom), the unlikely happens. People may say "we'll that may be a coincidence". I always say one event in itself may be perceived as coincidence, but coincidence ends when everyone has the same experience. My explanation is the use of telepathy. Your friend sends out a mental signal and you being on the same mental level pick it up like a radio.
