So, I have run into a bit of a problem. You see, I am currently creating a magic system for a second fantasy world I'm working on, and I am unable to figure out how to solve some of the problems posed by how the system itself functions. My question is: If a magic user has to enter into a dream-state, meaning they have to be asleep to use their magic, how would they protect themselves from harm? A few notes on how the system works:
These magic users, called Dreamers, are able to enter the "dreamworld" and shape reality around them when they are asleep.
They use powdered magic crystals called dreamdust to fall asleep whenever they need to use their powers.
When they are in the dreamworld, they inhabit a "spirit" body separate from their own.
Dreamers can "possess" golems made of dreamdust crystals using their spirit bodies, but do not always have access to these due to them being expensive and difficult to produce.
A Dreamer who is unusually powerful can control their physical body as well as their spirit bodies at the same time while awake, but magic users capable of this are extremely rare.
Lastly, Dreamers are responsible in most places for fighting the "nightmares", which are basically demons that inhabit the dreamworld.
Sorry for the information overload, but basically my question boils down to this: considering the factors listed above, how would a Dreamer defend their physical bodies while they are asleep without using their spirit forms to guard themselves?
