Oooohhhh I love it when things like this happen. I think its even stranger when for example you have the urge to call someone you haven't spoken to in ages (or see them) & then within weeks you find out they've passed away. It's wonderful that sometimes we get that urge to make contact before its too late!
Unfortunately mu mum had an experience like the one I mentioned above. She had a string urge to call her brother one night, she didnt get around to it & thought "Oh well I'll give him a call tomorrow night".
He died through the night (in his sleep, he was old). She was very upset that she didnt take the time to call him when she had the urge & I've learnt from what happened to her that if I have the urge to contact someone to not put it off.
But yeah, sometimes I think of someone then my mobile rings & its them! Freaky hehehe
