Heres a few pointers my friend shared with me when it comes to horror movies.
1. Understand that you have to make the audience feel the movie as if it was really taking place.
2. Understand its not everyday someone dies next to you or in fact that you are dying.
3. Mentally prepare yourself before the scene. You have to understand that there is a large shock factor in horror movies. If you realize this you'll twice as good.
4. After you mentally prepare yourself try to forget it. If your expecting it to much the camera and audience will expect it.
Try to stay very calm, the calmer you are the more the shock factor plays a part in the scene.
