The meaning of Mop in dream | Dream interpretation
A new or clean mop suggests that a pleasant hobby or community ac- tivity could develop into a profitable venture; but an old or dirty mop is telling you that you could soon be seriously embarrassed by neglected duties if you don’t make more effort.
You will need forethought and carefulness to avoid coming trouble.
See “clean” and “foundation”
Symbolic of the need to clean out an area of your life, Gen. 35:2 NLT
Used to clean floors and mop up water, a mop in your dream may point to a process of cleaning up after an emotional storm in your life such as in an argument or a disappointment. It may also point to tears of sadness that may need sopping up.
