Harry's lips pursed as he thought. His hand nearly went to punch up his glasses, something he still had a tendency to try to do, forgetting now that after years of wearing them, he no longer did. He continued the movement and simply scratched his nose instead.
"Dumbledore used to tell me almost anything was possible, good or bad. People, muggles, used to come up with things to explain what they couldn't really rationalise. A lot of religion's like that. The Greeks might not have been different. I don't think there were exactly jars of suffering and blessings, but there might've been something that ordinary people chose to explain that way."
His brow furrowed. "Hermione, I've been thinking that maybe this Dmitri Zurlo, whatever he was doing in the Department of Mysteries, maybe he set off something, something that caused all those nightmares to happen. It's a bit too coincidental, I think, him sneaking into that particular department, and then only the same night have wizards, witches and anyone exposed to magic all have some sort of strange unexplained reactions. Did you come up with anything about nightmares?"
