Dreaming of mire (or sludge) will avoid great danger.
Dreaming of falling into a quagmire, you will be bedridden.
Dreaming of crossing a quagmire implies unusual changes in things around you, which interrupts your most cherished wishes and plans and temporarily stagnates.
Former Duke of Zhou:
Through the mire, the main disaster came. Duke Zhou
Seeing the quagmire, the main danger is scattered. Duke Zhou
Deep in the mire, the Lord is seriously ill. Duke Zhou
