Dean nodded too. He'd had those, although they didn't seem to affect him as much as the chasing ones. "Mine aren't always the battle. Those ones tend to be more hazy and waking up to see people around me, knowing that most people survived," he paused, taking a moment to remember all of those who hadn't survived. "That helps, usually," he said, his voice taught with emotion.
"No, it's the ones where I'm being chased that I can't cope with. I wake up in a panic, imaging Death Eaters or snatchers inches from my face," he gave a full-body shudder, "my heart pounding as if I'd run miles. On those nights, nights like this. I know I'm not going to get back to sleep. The stars make me feel less trapped," he said, lying back as well. "At least Hogwarts is big," he added in the barest whisper.
