I dreamt I was tiny and scuba diving in the inside of my own closed mouth which was, from my diminutive perspective, the size of a stadium.   There were large mushroom stem-like growths everywhere, a forest of fungi stalactites.  I removedsmaller ones by pinching them off and larger ones by wrapping my arms around them and pulling.  I put the removed stems in a pile.  Then the pile grew a crust around it, like a clam shell, sealing up my mouth mushrooms.
