An opening scene of a horror film

This is one of the many horror opening scenes that my group and I have looked at, we have been looking at the sub genres in the genre of horror. There are a few sub genres i.e: psychological horror, survival horror, found footage horror, slasher horror, vampire horror, thriller and ghost. We have been looking at alot film openings around these sub genres but we are not sure about the type of horror to do we are drawn between a psychological horror and a thriller.
