* NightmareFuel: The whole movie has a strange, unnerving, psychedelic feel. The initial scenes in the submarine are also extremely claustrophobic, which explains Michaels's panic attack.
** Cora is attacked by antibodies in the inner ear, which causes her to scream bloody murder. She then complains of being strangled and unable to breathe. As if the claustrophobic feel of the movie wasn't enough.
** [[spoiler:Michaels' death - being digested alive by a phagocyte - is pretty grisly.]]
