Quicksand

Dreaming of quicksand suggests that an outside or internal force is stopping your progress. Sand is a symbol of time wasted as you might be in a place that only makes you suffocate. Feelings of hopelessness, anxieties, or fear of losing ground in competition with others, and emotions that engulf you.

Symbolic of a trap that can kill you, Ps. 69:2

Dreaming of being trapped in quick sand can be a message that the foundation of your established beliefs is undergoing a type of implosion. While self limiting ideas may be trapping you, the solvency of the foundation is actually a good sign that the foundation is being reworked. See also Dream Setting and Landscape and Scenery.
