What does it mean when....

you are loosing chunks of your hair in a dream? The dream was all jumbled, but at one point I pulled out a big chunk and was holding it up showing everyone saying LOOK! Look how long my hair has gotten! Then I realized, it wasn't attached any longer and started freaking out. I went to a mirror and looked at the top of my scalp and there were big sections missing. I was flipping out in the dream. Wonder if this has anything to do with my Mom going through chemotherapy right now? She hasn't lost her hair, though--interestingly enough.
