Hey Bet;

IMO would call it being in touch with the all knowing/energy/in tune or whatever name you feel comfortabel calling it.
And yes i would definetely talk to the person about it, if you make a mistake ...so be it..no harm done.
An exemple here: was just sitting outside relaxing/enjoying the beautifull day and a thought came to mind that a good freind of mine needed some healing energy, saw her sitting on the side of her bed at home and just thinking that she should call me and talk.So i grab the phone and call her, before she did..and she was sitting in her bedroom, thinking about calling me !!
Ex: 2- Another person that i know, who's a pentacoastal church goer, i know that he play guitar at church, that is a fact that i know....saw him playing the guitar at home, no big deal there cause i know he plays guitar at home, but i saw him doing something different after he finish playing, he got up to the kitchen area and started cutting fish for dinner, so i gave him a call and ask him if he just finish playing and was getting ready for dinner and cooking fish...he said yes..how do you know..??
Yes things happends like this more than once..and yes if you know the person ..call and ask, then it will be a "KNOWN" to you, and make you feel great and get rid of some blocks...

With love, Romain
