There was just an earthquake.
It was at 4:00 am exactly; five minutes before my alarm goes off. I got up, extraordinarily disoriented, and opened my door, which was rattling. I thought I had overslept, perhaps. I thought my parents were trying to wake me up, though my door was locked. I opened my door, and everything was silent, and there was no one there. Then my alarm went off. Which means this fit happened at 4:04 am. I slept through most of an earthquake.
No wonder it takes me forever to wake up after sleeping.
