nose

I couldn't breathe properly so i went into the bathroom to blow my nose. I looked in the mirror and when I blew I saw a lot of white stuff in my nose but I inhaled and it vanished. I blew hard again and saw it appear and quickly scooped it out. To my horror upon closer inspection it wasnt snot but some kind of shelless snail similiar to a slug. At that point I realized that I could breathe so much better and somehow I could see my bronchial tubes when I looked in the mirror.
