Hermione was in her element. She had spent all night poring over the books she'd taken from the library. Hermione was glad that she had chosen to look into more emotionally based dreams than their physical imagery. It seemed that dreams linked more to the psyche were likely to have magical cause than simple visual dreams.
"Rosalind Bungs mentioned that her dreams were more emotional than visual," she pulled out yet another book. "It would seem that a disturbance in energy flow is often accompanied with major nightmares. Often dark magic can be used to cause these interruptions in the general flow of the atmosphere. There are actually curses that can be used to get the effect, however they are usually more localized than what has happened."
She hated that at this point in time she didn't have anything more solid to share with Harry. She would definitely by cross referencing the legend of Pandora with various magical items.
