After stage 5, you arrive in what seems to be the final calm before the storm. Things are about to get worse, but here is where you'll be able to rest without being bombarded by enemies and obstacles, and you'll begin to find a way out of the astral realm. This stage would be an atmospheric place away from all danger. You would actually fall asleep here. During your slumber, information about the astral plane (History, enemy info, etc.) would be revealed in a dream, as well as the clue to the escape path (Which would be through the astral & auroral sectors).
