Ideas for my film opening

As our media studies class has moved on from doing practice in groups, I have noe thought more about my own film opening. I want my genre to be mysterious horror film, as I think it could be rather interesting to film and  this also means I don't have to included much dialogue which I didn't want to do because it would have been hard to think of a full script. As this is the first stages I will possibly change my mind, but these are my first idea I want my genre too be.
