I can not stop thinking about this dream?

Last night I had a dream that my biggest mentor wrote me a note saying that he cheated on his wife with a 20 year old girl, and that he was devastated that his wife was having another baby. I know that in real life none of this would ever happen; he adores his wife and he is so stoked about this baby(their 4th), but I just can not stop thinking about this dream. Help?
