The meaning of flail in dream | Dream Interpretation
Dreams of flailing are about processing your uncentered, unfocussed, feelings; you are releasing that you don’t know your rightful place. This dream could also be a call for you to stop running around and drop into your center via a meditation and/or your spiritual practice. Your dream is telling you not to move until you are moved by your higher guidance.
