"to dream that you are cleaning, implies that you are removing some negativity in your life and overcoming major obstacles. you are moving ahead toward a new stage in your life. in particular, if you are cleaning your house, then it means that you need to clear out your thoughts and get rid of your old ways and habits. you are seeking self-improvement. alternatively, the dream may be a metaphor that you need to "come clean" or tell the whole truth about some situation or matter."
