First Person Horror Films

Ok honestly i had some real good ideas for some horror movies in the last couple of years. I never do anything more with them because I'm lazy. However one of my ideas was to create a horror movie where the entire film was seen from only the main characters perspective. This is not the same as POV movies which are like Paranormal Activity, Blair Witch, or even Cloverfield. This is because in those movies the character are aware that they are holding a camera and shooting the entire movie from their cameras perspective. I think without the character holding a camera it would make it sick because the audience would only experience what the main character is always experiencing which makes it real twisted! Umm idk if the techonology is there to do such a film but in any case i think this would be an amazing leap into more original horror films. Give me your feedback and i hope that you all understood what i was trying to convey. That is all for now.
