"The plane simultaneously bucked to port and dropped hard. Sara felt weightlessness for a second. The floor shrank away, then came up fast and slammed into her face. Dull pain filled her brain like an alcoholic buzz. She couldn't focus. She blinked a few times, tried to stand."
The above is from page 260. I dont get the following: Does it mean that the floor actually hit Sara on the face (which I find a bit weird) or that the feeling of weightlessness made her feeling dizzy?
