A mouth can stand for a need to communicate, particularly about something that is bothering you. It can also stand for a part of you that is selfish and demanding.
Dreaming about an open mouth can be a sign that you are receptive to a new idea or way of thinking.
However, it can also mean that you have been saying too much and it is time to close your mouth.
If you dream that your mouth has been sewed or buttoned up, you may be sorry for something you have said or done.
A dream that you are pulling something out of your mouth can mean that you need to express your feelings.
You use your mouth to speak and to eat, so a mouth in a dream can represent self-expression or nourishment.
If you have a dream about a mouth, you may want to express yourself better, or you may be concerned that you are not communicating well with others. This dream can also indicate a need to nourish yourself emotionally or spiritually.
A mouth in a dream can also represent a part of you that is selfish and demanding, particularly if the mouth is very large.
If you have a dream about a huge mouth, you should think about how you have been behaving. Have you been considering the needs of other people?
