According to their deeds, they would receive some rewards for their actions. However, they would also suffer in proportion to their ego and sleeping consciousness. Thus, such a person might briefly poke their head out of hell, but inevitably falls back in.
...any attempt at liberation, no matter how great it might be, if it does not take into consideration the necessity of dissolving the ego, it is condemned to failure.
I just re-read your response now and will add.
As for the sleeping unconsciousness, I was originally thinking that with enough Dharma/good karma, this could potentially provide a rebirth (albeit unconscious) into a similar or slightly better existence e.g. in the physical plane, in another galaxy, as a humanoid extra-terrestrial who can continue Dharma. On top of this, I originally thought that with enough good karma, this would also over ride the entry into the inferior realms, even when there remains some ego. However, I see now that that is not the case since the inferior realms only exist as long as the ego's exist, since they are one in the same.
I may make another post in the future questioning the rebirth in those realms since I so far am not witnessing much hell in my dreams and do not experience such hellish karmic repayments within my waking life either.
