This was just a fragment of a larger dream I can't recall. However, I was looking in the mirror and it appeared that I had dandruff. I started to scratch at it frantically in my dream. It felt like it was burning. As I'm scratching at my scalp, I realized it wasn't dandruff at all, but white porcelain glass. It started falling to the ground in huge shards and shattering. I kept scratching. My head had turned into part of a porcelain figurine. I was half broken by now.
