V. "Dreams/Nightmares"
Orihime had often thought how pessimistic the English language was to have no word that opposed "nightmare". When she said that, people would argue, "The opposite of a nightmare is a dream!" but she found that to be untrue. Dreams were merely the standard: an odd, all-encompassing word that housed its own subdivisions. Nightmares were dreams, after all. Bad dreams, but dreams nonetheless. So if Hell were a nightmare, then dreams would be Limbo. But where was Heaven?
During her stay in Las Noches, Orihime had become familiar with many different levels of Hell. Each was governed by a different man, but each was as equally torturous as the next. One was governed by Grimmjow Jaggerjack, who tried to break her with his fists; another was governed by Ichimaru Gin, who tried to coax her spirit out of her with his toxin-coated tongue; another was governed by Noitora, who was less interested in her spirit and more interested in her body; and the last was governed by Aizen himself, who tried to pry apart her soul with his bare hands.
She considered them all to be Hell. They were all nightmares. But every so often, she would get a glimpse of something more. It wasn't Heaven, but rather a midway point that was neither righteous nor evil. That last sanctuary was Ulquiorra, and he was her dream among nightmares.
