To dream of an undertaker represents a concern with being perfect in how you end a situation or relationship. Planning or considering all aspects of a situation that you believe will end soon. Wanting to “bury” a relationship, problem, or situation with no problems at all.
Negatively, an undertaker may be a sign that you are dangerously accepting of a potential failure as inevitable. A fear of an inevitable failure or unpleasant change. Alternatively, it may be a sign that you are allowing your competition to totally humiliate you with your impending failure. Being too passive about potential losses.
Example: A woman dreamed of dead people sitting upright in an undertaker’s office. In waking life she was aware of a strange developing illness and choosing to do nothing about it. Instead she was considering planning for her own death. In the end she was found in a coma and properly diagnosed.
