In many cases, to dream you have the urge to urinate stems simply from the physiological needs you experience while you sleep. Sometimes this dream also refers to sexual desires. The urine, however, can represent all the things we get rid of or reject. You are trying to clean up your Interior, so you leave behind all you think is not worth it. For many centuries, urine has been considered the ultimate protection against ghosts and evil spirits. It was also believed that if a girl urinated in the shoes of a man, he would fall head over heels in love with her.
