Working Definition
The Form is the name for the region that encompasses everything.
Every dream-space appears to exist inside it.
Dream-Spaces
A dream-space are the physical spaces that exist within dreams.
Dreams can be possibly accessed by something moving within The Form itself.
The dream-space itself should be treated as neutral.
Restoration Theory
Sleep still restores the brain and body.
The question is whether that restoration is only biological.
Every sleeper seems to enter a dream-space, even when they remember nothing.
I cannot separate those yet.
