You may not have progressed on a subconscious level beyond a feeling that anything to do with bodily functions is dirty and self-centred.
There could be an element of rebellion in your waking life. Playing with excrement can represent your attitude to money and value, highlighting fear of responsibility, as well as anxiety about money.
If the excrement is transformed into living animals, maybe rats, you are accepting that you are responsible for managing your own impulses. Excrement in its more spiritual meaning belongs to the realm of feelings and you may simply be trying to get rid of bad feelings.
Those bad feelings can be turned into something worthwhile. Evacuation of the bowel usually highlights our need to be free of worry and responsibility, or possibly the need to learn how to be uninhibited.
It can also signify the sexual act.
