Looting the house

Waking up the next day, Mark looked at the window and noticed the dewdrops on it from the chilly wind at night. He then turned towards Suzie, who looked like she slept peacefully enough last night. But when he squinted his eyes, he noticed she clutched the bed sheet so hard that there were holes in them. Her palms had red markings on them. 

He shook his head, but still sighed in relief. This was progress. Unlike last time, even though she struggled, she was still able to sleep without shaking or waking up in the middle of the night. He checked the time and found out it was 6. So he stood up and gently shook her body.

"Suzie, wake up. We got to go." But as he did, her body jerked, and she woke up. She looked around as if she was searching for something. Mark immediately patted her back and said, "It's alright. It's no one, only me." And only then did she cool down a bit.
