You can get mind states that are ambiguous mixes of awake and asleep.
I am having trouble parsing this statement. Does it mean that when simulating a mind you could also simulate ambiguous awake/asleep in addition to simulating sleep and wakefulness? Or does it mean that a stored, unsimulated mind is ambiguously neither awake or asleep?
There are states that existing humans sometimes experience, like sleepwalking, microsleeps ect that are ambiguous.
Whether or not a digital mind is being simulated is a much crisper definition.
