Sequence

For my sequence Im choosing to do the narrative disruption, what happens is:
At the beginning of the sequence, the audience is shown the attic and will zoom on a small rocking chair which will move slightly, it will then cut to outside the attic near the steps where something will be thrown down from the attic and be shown falling down the steps. Before zooming in on the object and then going back to show the 'Grace' the ghost girl stood on the steps before moving down to the floor. It will then switch to a shot of the radio on (bars moving on the screen) and then 'Sammie'  and 'Russel' asleep (Sammie on the bed and Russel sat on the floor) before switching back to the door opening. Showing grace walking into the room, then a shot of radio silent and then standing over Russel lifting a heavy object (yet to be decided) over him. Close up on 'grace' about to drop it when it switches to 'Sammie waking up and then showing a pan round the room showing no one there. Next shot will be the the door slamming and then showing 'Sammie' and 'Russel' jumping up.
The reason I chose to do this sequence is because it is the first time the antagonist is introduced to the 'Sammie' and 'Russel' so it is the narrative disruption. With the genre being Horror it is the first time in the film which the genre becomes obvious as I want to make the shots quite short to build up tension.
