Astral Searching

Peculiar dreams with an irresistible man have been preventing Hermione from properly resting through the night, thus making her recovery from the final battle that much more difficult. She was exhausted, irritable and, more than anything, so very confused.
While staying at the castle with Ron and Harry post-battle, Hermione learns that Professor Snape, whose body had been missing when they went back for him, was in fact alive. Where he was, however, was unknown. This worries Minerva, who has considered the man a friend despite his unwillingness, as well as Harry, who felt he owed the older man a great debt.

What is happening to Hermione? Who is the strange man haunting Hermione night and day? And where is Severus Snape?
