Ideas for own film trailer

With the research I carried out investigating real Psychological Thriller trailers, I looked at the scenes, icons or storylines that inspired me to help with creating my own psychological film trailer.

Below is a small brain storm I created with a few different ideas for a film.

After looking at this plan and putting it into perspective with what I resources I had and what I could achieve with what I had available, I created a rough idea for my film, looking at my inspirations and the icons I will focus on.

Brief main idea: Focus on a young girl who's life is going very smoothly and life appears very normal (Barthes- events do not arouse suspicion). But then small events start to become eerie and spooky, causing suspicion to what the girl's life. Reflections start to become obscure, icons such as masks and blood start appearing in her day to day life and she is constantly questioning her own motives as the trailer goes on.

Icons: Masks, blood, obscure reflections. 

Main inspiration: Black Swan, Donnie Darko
