Hello

I just had this a bizarre dream.

I had to dive deep in the sea to kill a monster and loot treasure from his corpse. This was not a Sea Dragon and it didn't really look like a mythical creature, just a standard ugly monster.
I killed it with practically no effort and looted the treasure from his corpse.

I brought it back to the person who gave me the quest (can't remember how he looked like). 5 minutes later though a sea dragon attacked the city and went to it to fight it.
When I confronted the sea dragon with my sword the dream ended and I woke up.

What could this possibly mean?

I see a few things in this dream that are metaphorical. First, the monster in the sea could represent the monster within you. Do you anger easily? Water, or in this case, the sea, could represent your emotional state. The treasure buried in the monster could be your hidden potential. Are you artistic or are you interested in perusing an artistic talent?

That part of the dream could also mean something good coming out of an ugly situation. There's a "monster" inside you (this could relate to your emotional state) but also inside you is a hidden solution to the problem or problems. Since it doesn't take much to kill it, you know you can handle it and find a simple solution.

The sea dragon on land could mean you feel "out of place" like the sea dragon is out of place. He should be the one in the sea, but he's on land. This could be that you're already working on a solution to a problem. You recognized that the sea dragon should have been in the water, not the monster and you are trying to sort things out, put things in it's proper place so to speak, or proper perspective.
