When two separate things with opposing interpretations are seen in a dream then the stronger or better of the two interpretations will be given. As an example is a person sees a bathroom and himself as removing hair using a lotion or lime-whereas a bathroom represents grief and sorrow and removing hair using a lotion or lime represents the removing of grief and sorrow- it means that his grief and sorrow will be removed, for the dream of removing hair using lime or lotion is regarded as stronger or better.
