Interesting. This looks like it would be good for other host to get into as well, since they could be better at actually forming the Dreamscape.

Personality could be added to the character sheet, for both in and out of the Dreamscape.

What happens when you get hurt or die in the Dreamscape? Is your ability to enter the Dreamscape destroyed? Does your Physical body show signs of the injuries? Or is their no affect? 

What about daydreaming? Can you only enter the Dreamscape at certain times? Or can it be entered at any time? 

What about location? Does it matter where you are in the "real" world?
