you were in class,just taking a boring test,until your teacher walks out of the room,hence leaving all of you alone

you and your classmates start sharing answers since the teacher left,and as you look around,all of a sudden,you see your teacher staring right at you,and you realize she's ON TOP of the LITERAL ceiling of your class,it seems she is near one of the ceiling tiles she must have removed,you can see the vents of the school right in front of her
