Crocodile attack in a flooded Dorm

"I was asleep in a room that wasn't mine, more like a dorm with a few beds lined up. It felt oddly comfortable, and I didn't question it. At some point the floor had turned to water, rising right up to the sides of the beds. Suddenly a crocodile burst up from under my bed and lunged for my arm. I fought back, punching it until it let go and slid away. I sighed with relief, but it was too soon. Another crocodile struck from the other side of the bed, and this time it caught my forearm, its teeth sinking in deep. I woke up gasping in pain, sitting bolt upright and clutching my arm. My heart was hammering, and it took a few seconds to understand there was no water, no crocodile, and no bite. My forearm still tingled, and the sudden jolt kept me on edge for a while."
