The Nun-https://www.youtube.com/watch?v=KvSCsNFokak

Before sound:
In the nun film trailer when I watched it without sound it did not look right at all. It is meant to be a jump scare horror type of film and whenever there is a jump scare the nuns run out or brake something and the same effect is not there. Also when it cuts to an image of it saying before the conjuring and before annabelle it confuses me as I don't know why its said that there's no sound so I don't understand why it's happening and nothing makes sense.

After sound:
The narrative explains that thenu is part of the conjuring universe containing the conjuring films and annabelle films. It makes a much bigger effect then having no sound at all. The music makes the trailer more intense and makes you feel like you are in the trailer.
