Hermione went straight home when she left Minerva's office. She was already off from work, and it was too late to go in anyway.
She found herself too distracted to read, which was unlike her, and decided to distract herself. She cleaned the house for hours. It wasn't that the house was dirty, but she tackled the dust, the undesirable jobs, and everything in between. She even did the laundry which she normally left for Severus.
But still her mind wandered. She kept seeing her nightmare in her mind's eye. It was as if it was haunting her from the inside now.
