To dream that your boat has capsized indicates that you are reluctant to face an embarrassing or awkward issue.
To face this would mean that you would have to admit that it exists. You are not prepared to confront these feelings yet.
Dreams of a boat being capsized symbolize that you are feeling off balance. Perhaps you feel overwhelmed by your circumstances and are in need of support. This dream may be showing you that you are rocking the boat, or that you fear that your ideas or leadership will be overturned.
