Clearance
To dream of a clearance sale represents your realization of some area of your life suddenly becoming easier or undervalued. Experiences or possibilities that were out of reach are now too easy. A person or opportunity may be proving itself to be desperate.
Alternatively, a clearance sale may represent your eagerness to "clear out" or get rid of some area of your life. It may also reflect your desperation or that you are undervaluing yourself.
