Upon going to sleep with a cold the mucus from your nasal drip slowly seeps into your bowels, resulting in the semi digested mucus exploding from your rectum. The mucus is likely to grab and carry the remnants of previous shits with it into the toilet. The mucus gathers on the surface of the water, creating snowflake like formations.
