Is there a word when you think of someone and he suddenly shows up or calls you ?
Could the word you want be synchronicity:-
- Coincidence of events that seem to be meaningfully related, conceived in Jungian theory as an explanatory principle on the same order as causality. [American Heritage Dictionary via the Free Dictionary]
Probably most accurate is "anomolous experience".
I've heard this meaning associated with "premonition". Some people say "sixth sense" (but, more technically, psychologists will call it an "anomolous experience" which is why I mentioned that first). I've also heard this intended meaning from the phrase "feminine intuition". Men will often say "gut feeling" or something more along those lines.
Here's an on-point article from Psychology Today: http://www.psychologytoday.com/articles/201206/your-sixth-sense
