'The Possession' Scene Deconstruction

• The very white and pristine hospital theatre where the main (possessed) character of the film, "Em", receives an MRI scan has strong connotations of purity and innocence. This juxtaposes prominently with the nature of Em's possessed-like acts that are being investigated through the medical procedure. 
• The voice-over telling Em how the procedure will take place is heard over a microphone as if the audience is the patient in the MRI scanner. The voice is very low and is quite ominous which is lends itself well to the build up of what the audience expects to happen as they know Em is possessed. 
• Em's sister, Hannah, can be seen crying in the foreground of a close-up shot while Em is being prepared for the MRI scan in the background out of focus. This makes it obvious what Hannah is crying about and conveys to the audience that the upcoming events are something to be concerned about and that they are likely to be linked with possession, conforming to the supernatural horror genre.
• During this shot, the diegetic sound of Hannah crying can be heard while she is on screen. This is done to show the audience Hannah's concern which is made a prominent aspect of the sequence.
  
  
• The loud whirling diegetic sound of the machine moving Em into position is the only sound heard at one point. This is a very unnatural sound and is also quite dark which is contrapuntal to the shot of Em being moved into the MRI scanner but on the other hand, lends itself to the build up to what the audience anticipates to be a climax which incorporates possession.
• The continuous pulsating sound of the MRI scanner taking photos of Em's brain is also quite ominous in the way that it seems as though it is building up to a climax of some sort. The diegetic sound creates tension and anticipation and also intrigues the audience and holds their attention.
• The spirit which has possessed Em can be seen in the MRI scan towards the end of the sequence. Although the face is clear within the image, and there are no cliched 'jumpy' parts to scare the audience, the crescendo of the diegetic sound creates tension and with the image, it succeeds in scaring the audience in a more subtle manner.
• Despite a prominent build up achieved mainly through both the diegetic and non-diegetic sounds, it ends with an abrupt change to a low piano note (non-diegetic) as part of the background music with no use of diegetic sound as Em's mother rushes to pull her daughter from the MRI scanner. This creates quite a morbid feeling where the family can be seen crying over the past events.
