What does it mean when you dream sharks in dirty water?

It could mean a number of things. Maybe you heard about sharks and dirty water recently. We regularly incorporate current events into our dreams.

If it is a symbolic dream, you'd have to figure out what the components of the dream mean to you. For instance, many people use "sharks" as a derogatory term for attorneys. So many people think that attorneys are "dirty," or they think of financial matters as "dirty." So it is possible that the dream is about legal or financial trouble, or a fear of such.

Or maybe sharks represent a more general fear for you. The water being "dirty" would mean that the water is shallow, and outside of a shark's normal habitat and closer to humans. So you may be afraid that life is closing in on you, that there is trouble out stalking you. You might not be in the water, but the sharks are trying to get out.
