I approve of this idea.
Dream ideas:
You are a wolf (
) and your pack is on the hunt, meet/fight hunters/bigger creatures and either die/succeed/run away as your allies fight. Or maybe have a more awkward adventure, maybe get lost from the rest of the pack.
You are a goblin/troll and get to do troll type shinannigans such as chucking mud/bodily fluids ate pesky nords.
A nightmancer (Can;t think of a better name) visits your dream and turns it into a nightmare, your freedom is stolen (Limited or no mana etc) and you must get rid of him and save the life of a fellow dreamer (A dream quest XD).
