Assuming the dead fish in the dream is rotting on the beach - or somewhere similarly distasteful - it means that something you had hoped for is ruined. Instead of being tasty or useful, your plan or project or idea needs to be tossed away so that it does not "stink up" your next endeavor.
If the question is referring to a dream about a dead person and a dead fish, it could mean that the dreamer is feeling rather hopeless. Beyond that general suggestion, the dream's meaning would depend on who the dead person is and what relationship they have to the dreamer.
It mean's your brain was thinking about fish while falling asleep and focused on it.
That depends on the severity and how often you dream them. In this case the dead fishes would be known as Latent Dream Content or the things we don't understand about a dream that often have some deeper meaning. The mob used dead fish to convey the sense that someone was about to be killed and thrown into the ocean hence the saying "Sleeping with the fishes". Your dreams probably mean nothing serious...unless of course you disrespected the mob in some way.

Nothing.A dead relative is simply defending you in your dream. Does there need to be a meaning for everything?
Well long story short, you dream about the dead, or do you mean the undead (i.e. zombies, skeletons etc.)?
