The Big Dictionary of Dreams

by Martha Clarke
This dream represents the spiritual energy and purification. You are finally clean, washed, and ready to begin again. Down the drain go pain, sickness, and worries.

Showers can be a symbol of healing. There is a technique we can all practice: imagine yourself under running water that washes you outside and inside. Next, you are filled with light, from your feet to your head.

It is quite possible that this dream has given you clues to carry out your own self-cleaning.

It is worth trying it in real life.

If you are dreaming of taking a shower, then you want to cleanse something in your recent past and let it go.

If someone in your dream is taking a shower, consider what aspect of your personality the person represents, as that is the part of your psyche that has something that needs to be released and cleaned up.

A cold shower is a symbol for balancing out an overabundant sex drive.

A shower that is too hot indicates that the need for purification is at an even higher level.
