The bathroom in dreams is known as the symbol of clean mind and soul, because it is the place where people take the shower, wash themselves and take care of their bodies. If the bathroom is clean and tidy, your mind and soul are as clean as the bathroom is. If the bathroom is very dirty or simply messy, you should look better after yourself. Perhaps you have too much stress and experiencing negative emotions. Make sure you get rid of it as soon as you can. If you are in the bathroom with someone else, it shows your desire to interact with this person better then you did before.
