To dream of being sucked into quicksand indicates you may be in an emotional bind in your waking life. An activity you are participating in is producing a feeling of judgment, whether of another person or yourself. This may be draining you of important life energy. There is courage needed to pull yourself free from the influences that are keeping you in this negative vortex of attraction.
To dream of pulling another person or yourself from quicksand is alerting you that you can turn around your situation now.
