Little Boy Coming And Going

The other day when I was feeling really low and depressed I was talking to Zack when all of a sudden there was this little boy who just appeared out of now where and it kinda freaked me out a bit, the strange thing is he just came and said a few words that made me feel a little betta and then just like that he was gone, so I would like to know what that could mean, because it was the first time that either of us had eva seen this little boy, he had no name so we gave him one, we called him Billy.
