In the first dream I fight a girl who turns into a male mannequin: She can swirl her arms around and over long distances. In the second, I fight two hunters (one in ranged combat who runs away, another one in melee whom I defeat). In both cases I emerge victorious but not without difficulty.

Well, I think the people you are fighting are parts of yourself. The girl turing into a male mannequin could have to do with subsituting "feminine" powers of intuiton for "masculine" powers of logic and reason. A mannequin is also devoid of feelings. I'm guessing that the hunters are hunting you? Hunting can interpreted as "searching", so there could be something that you don't want to find out about yourself.

Mhm... Could be. Normally I try not to rely on intuition as I find it very confusing to determine the "Should I or Should I not?" when working with it.

Perhaps a little more of context would help? In the first dream I am climbing up stairs and then meet a girl in a lonely floor, who is at first happy to see me then gets angry when I ask a spefici question. She would not let go of my hand then she throws me into a room; I mock her attempt to write "hell"* in the room's door by writing "welcome" myself (and mockingly thanking her for the welcome). Then her friend comes by, and the first battle ensues - however the first girl never lets go of my hand.

Before the second fight, I and a (male) friend are trying to spy a certain fair. Then the first hunter comes by and, instead of running like my friend, I duck for cover and fire back. The hunter is then replcaed by the one who lacks a hat and fights me in melee**.

Both dreams have rather big contradictions I noted:
*Despite the name, the "hell" is actually a room full of snow and blue/light blue and white.
**We are fighting in melee but we are using our ranged weapons as if they were sticks or clubs.

As always thank you for your replies.
