Dreaming about a chimney means the need to cleanse and purify oneself. You need to seek out the negative thoughts, feelings, and memories that are clogging up your mind, then the spiritual cleansing and renewal will take place.
The chimney is usually related to a house or a home. It could be that you are feeling disconnected from your family or you are feeling like you don’t belong. In some cases, people who dream about a chimney are trying to express their feelings about being trapped in their current life and wanting to break free.
