She was dead, right?  Yeah, she definately died.  There was no way she'd survived that plane crash.  But then, why was she thinking?  [i]How[/i] was she thinking?  Was this the afterlife?

This train of thought was the spark that restarted MacKensie's five senses.  The first thing she was aware of was her heartbeat, which would steadily begin to quicken as her anxiety grew.  The air was musty, and above the faint sound of the her own breath, there was a throbbing hum coming from... outside?  The questions began to pile up on top of the already important conundrum.  She moved her hands and reached around to find that she was in an enclosed space, and that's when her eyes shot open in fright to total darkness.

Forgivingly, she wasn't made to panic in the claustrophic environment as the front of the box popped open and the young woman rushed forward to freedom, tripping in her hastiness and sending her tumbling out of the stone coffin, unceremoniously onto the floor with a whiney shriek.  The pain from the fall had her fleetingly think that this was absolutely [i]not[/i] the afterlife.  She looked at her outstretched arms, not recognising her clothes.  Her eyes went on to spy the dimly lit room, the strange glowing blue light in the walls, and eventually the seven coffins behind her.

She gasped, paling with fear, eyes wide.  There were literal coffins in the room.  And yes, she had just jumped out of one.  Butt-scooting away from the wall with the coffins, as others began to awaken, MacKensie was way past screaming in alarm.  She was mute, at this point. 
 She simply rose to her feet, against the opposite wall, an unwilling spectator to whatever might happen next.
