In the movie, Close Encounters of the Third Kind, the main character is "drawn" to a specific place along with people all over the world. He doesn't know why or for what purpose, but he just knows he has to follow his gut.
That is what I feel like we are doing. All of us are complete strangers from all over the world, but we were "drawn" here by some force or feeling involving Michael. I am not saying he is an alien or anything
, just that I think it is really neat and fascinating.
