The meaning of urine, urinating in dream | Dream Interpretation
Vision: Dreaming about urinating: it may just be an actual need to relieve yourself.
If that’s not it, relief from a difficult situation is in sight. Dreaming about wetting your bed: practice more abstinence. Drinking urine in a dream: the urine is a symbol of the medicine you need to take to improve your health.
Depth Psychology: Excrement and human waste products are a symbol of relief, of letting go, and setting oneself free. Reacting with disgust means that you’re afraid others will not accept you. See Excrement.
