DreamsMaster: Poo in dreams often symbolizes unpleasant or personally unacceptable negative thoughts and feelings.
If you are doing it, then it may represent that you have the need to release some unpleasant emotions. For example, you may be harboring anger or resentment toward someone close to you, and you may be feeling guilty about having these *shitty* feelings. Or, you may be having a tough time with your job or your boss, and are in need of relieving yourself of some pent-up frustration.
If you dream of wiping your own baby’s poo, it’s possible this means you are holding back unpleasant or negative thoughts and feelings about parenting. It’s generally not socially or personally acceptable to have ambivalent feelings about one’s child or the role of parenting, but it’s a very common experience. Our feelings need an outlet, and it’s not uncommon for them to express themselves subconsciously in our dreams.
If you are wiping an unknown baby’s poo, this could represent trying to wipe away negative feelings about your own early childhood, or about having children in general.
Consider all of these possibilities, and go with your felt sense about what your dreams are trying to communicate to you. If none of these ideas fit, check out more dream interpretation techniques on Dreams.com.
