chunk: David completes telling his story to Curtis, who proceeds to then visit David further for more sessions to try to help him recuperate. During one interview Curtis tells David the staff reported him calling out "Ellie" in a bad dream and asks who she is. David later sees a nearby TV advertisement for "Life Extension", a company that specializes in cryonic suspension, and realises he'd actually called out "L","E". Under Curtis' and a police officer's guard, David is taken to the Life Extension offices, where the salesclerk Rebecca (Tilda Swinton) explains they freeze people just after the point of death, until a cure for their ailment is available in the future, keeping their brain active by placing them in a lucid dream state. David becomes anxious and breaks free of Curtis, realizing he is in his own lucid dream that has gone wrong, and calls for tech support.
