Everything Went Dark
You are correct. Here's what happened:
Jennan hadn't woken up. She had a very realistic lucid dream that caused her to actually leave her dorm. She made her way to the kitchen where Jack watched her take the pot and leave. He didn't think much of it, though. Jennan then went to the laundry room and smashed the pot into Emma's head. Jennan dropped the pot and walked back out. Now, in her dream, Jennan was actually defending herself against some monster and was about to go conquer the monster king. There was no monster king. However, there was a defenseless, completely asleep Tatum. After "defeating" Tatum, Jennan went back to her dorm and went back to bed. When she woke up, she noticed she had blood on her and her clothes. It wasn't hers. Jennan started to piece things together. She ran into Jack in the hallway. He had also pieced things together, but promised to keep it a secret.
