The category "the dead" is far too broad to risk any single interpretation. Your dream's meaning depends on whether "the dead" in this particular dream referred to a beloved friend or relative, such as a grandmother, spouse or child, or whether "the dead" were overly dramatized Zombies or Horror film ghouls. The website linked below provides extended discussion of these and other possibilities.
what does it mean to dream dead peopletake you to with them
Mourning...
NOTHING
I this dream last night, it was strange.
Well long story short, you dream about the dead, or do you mean the undead (i.e. zombies, skeletons etc.)?
This dream suggests that an issue that was thought to be resolved (dead) is still causing problems.
Nothing.A dead relative is simply defending you in your dream. Does there need to be a meaning for everything?
Nothing, what you dream has no meaning in the waking world.
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.
You are a FREAK
you will stay alive for a long time
The meaning of this dream depends on who that dead person was. For example, a dream about your grandmother who passed away years ago would mean something quite different than a dream about an ancient historical figure or a long-dead celebrity.
