A lake in a dream often represents a hidden source of power. A dream that you come upon a lake or lagoon can be a sign that you have inner resources that you did not know existed.
You may dream about a lake when you have a problem that you do not know or how to solve or when you feel trapped in a situation that you believe is out of your control. Your dreaming mind is telling you that if you look within yourself, you will be able to find the resources you need to solve your problem or improve your situation.
A lake in a dream can be a symbol of emotion.
Swimming in a lake in a dream can mean that you are learning to handle difficult emotions. If you are drowning in your dream, you are finding your emotions overwhelming.
A lake in a dream can be a symbol of feminine power – the power of intuition and the power that comes from, paradoxically, remaining passive.
