Because of way that it creates an indentation in the shore, a bay in a dream is a symbol of the female body and of female sexuality.
If you are a woman and you dream about a bay or inlet, you could be experiencing sexual feelings or thinking about your sexuality.
If you are a man, a dream about a bay may also have sexual connotations. It can also mean that you are learning to accept your intuitive feminine side.
Because a bay symbolizes the entrance to the womb, a bay in a dream can symbolize the “birth” of something new in your life – the start of a new project or the beginning of a new stage in your life.
Water itself represents the emotions and the unconscious, so a dream about a bay can represent the encroachment of emotions and repressed unconscious thoughts on plans that have been created using a practical approach.
