I had a dream last night in which I saw myself taking a bath..It was a strange dream.I was just smiling the whole time (in the dream) and i was just washing my hair and singing and smiling.
What could it mean ?

Washing or bathing in dreams may stand for a need to rid yourself of something you regard as harmful. Washing your hair refers to emotions, so you may be trying to get rid of something that is emotional harmful to you. Washing hair can also specifically refer to the desire to rid yourself from someone in waking life, going along with the phrase "Get out of my hair." Singing is a representation of joy and a love of life. Further more, singing alone shows that you have learned to enjoy your own company. This may suggest happy feelings you would feel being rid of this person you are trying to get "out of your hair." This could be a nosey friend or a clingy partner.
