The anus can represent childish behavior, since a child’s first experience of control is control over his or her own bodily functions.
Dreaming of an anus can be a sign that someone in your waking life is anal retentive, that is, overly obsessed with small details.
If you dream that something is wrong with your anus, like it is bleeding, it could be that your subconscious has noticed the possibility of illness.
When you are very small, your anus is one of the first things that you learn how to control, so a dream about an anus often has to do with self-control.
If you dream about an anus, you could be worried about not being able to control yourself in a particular situation. Your dream could be telling you that you need more will power.
On the other hand, an anus dream could mean that you are too controlling and you need to be more relaxed about things.
A dream about an anus can also mean that you are “holding things in” – repressing strong feelings.
Because an anus is a passageway for waste, a dream of an anus may also have to do with getting rid of unproductive thoughts and emotions.
