Echoes said:"Dream templates": excellent idea.
Crazy dream god: excellent idea.
On an unrelated point: how are you going to handle people who access the dreamscape from methods other than dreaming? Or will there be no other way to enter? I'm talking about spellcasting means or perhaps some sort of drug/trance-induced trip to the dreamscape. Would these people have full access to manipulation of the dreamscape?
Also totally unrelated: Anyone here see Richard Linklater's awesome movie "Waking Life?" It's deeply philosophical and about the boundaries between death/life/dreaming. Not necessarily fantasy-related at all, but great for the kind of surreal mood that one might try to evoke in a campaign involving the dreamscape. And the animation of the movie is wonderful, to boot!
Laters,

For those that enter the dreamworld via magic or portal or what have you... they will act as if they have the awakened template with the notable exception that they will take real damage. At least that's my concept thus far... Note: Otherwise characters drawn into the dreamscape by magic retain their otherwise template in the stead of gaining the awakened template.
I'll have to see if anyone I know has the movie... might be good to watch ;-)
