The significance here varies according to the details and action.
If the creek was dry, it portends a disappointment probably to do with business; if it had a normal amount of water running, it augurs some pleasing new experiences; if you were swimming in it you can expect some exceptional luck to come your way; but if you only observed others in it you are being warned to pay more attention to your own interests or others may benefit from your efforts.
[1]To dream of a creek, denotes new experiences and short journeys.
If it is overflowing, you will have sharp trouble, but of brief period.
If it is dry, disappointment will be felt by you, and you will see another obtain the things you intrigued to secure.
[2]To see a creek in your dream, represents your energy flow and the healthy expression of emotions.
To see a dried up creek indicates that you are out of touch with your own spiritual side. You may also feel physically or emotionally drained.
[3]If dry it means that nothing emotional is happening in your life now.
If there’s water, note the flow, gentle = harmonious; heavy = you’re going through a lot.
