Dreams dictionary: Shower

Dreams dictionary: Interpretation 1
To dream that you are taking a shower in clear, fresh water symbolizes spiritual or physical renewal and forgiveness. You are washing the burdens out of your life. Alternatively, the dream may be a metaphor that you are "showering" someone with gifts or love.
Dreams dictionary: Interpretation 2
To dream that you are taking a shower in dirty or muddy water implies that you are feeling unclean about a situation. Dreaming that you are unable to take a shower or that the shower is not working properly means that you are unable to shed some burden. You are feeling weighed down by your emotions or by some responsibility.
Dreams dictionary: Interpretation 3
To dream that you are showering with your clothes on means that even though you may change your outer appearances, it does not change who you are on the inside. Alternatively, your dream indicates that you are unwilling to let your guard down. You are still keeping up a protective barrier between you and others.
Dreams dictionary: Interpretation 4
To dream that you are showering with someone suggests that there is something that you need to "come clean" or confess to this person. It is time to be honest. Perhaps the dream is telling you that you need to let down your guard. If you are showering with a group of people, then it means that you are feeling exposed. You feel that your sense of privacy is being invaded.
Dreams dictionary: Miller Dream Interpretation
