Disorientated
One of the strangest things that happen to people is a sense of disorientation when they wake up. That’s because they forget where they are or lose any concept of time. They may freak out because they think they’re late or have missed an important event.

“This morning I woke up and couldn’t remember what day it was and if I had my training class this morning,” Salol wrote after a moment of terror. “If I miss one class, I’m fired. Luckily, I was just paranoid and went peacefully back to sleep.”
