Old Faces

Something very strange has been happening to me over the last few months. I have been having recurring dreams involving friends from my childhood. At first it was just school friends, but now it's camp friends too! What's really disturbing is there is always something bad going on in their lives- like they have cancer or are getting divorced. Even though I'm not disturbed by these occurrences within my dream, I am when I wake up. I wonder what these dreams signify.
