Urine in a dream often represents emotions that you are keeping to yourself. Because urine is a form of waste, these are probably emotions that you consider harmful or unproductive.
A dream about urine can tell you something about how well you are controlling or hiding your emotions.
It is very common to dream that you have to urinate but you can’t find a place where you can urinate. Such a dream can mean that you feel that your emotions have been all bottled up and you have no safe place to release them.
The details of the dream should give you some idea of what is making you feel that you have to hide your emotions. In your dream, are you there always people around so that you have no privacy when you need to urinate? This could mean that you are afraid that your “secret” will become known to the wrong people. Is the bathroom in your dream too dirty to use? This could mean that you are ashamed of your feelings and believe that others will look down on you if they become aware of them.
A dream about urine or about urinating can also be a sexual dream.
