**possible spoilers** I really enjoyed this movie, but I have some questions that hopefully someone here can help with. The whole beginning sequence confuses me... was that Johnny in the walls attacking Patricia? And if so, why? And if not, who? Her father maybe?? And we know that Frank had a traumatic experience that changed his perception, allowing him to see the ghosts, but why can Patricia and her mother see them? And what was her mother yelling about her being "too young", and "sins of the flesh", or whatever it was she was yelling??? And lastly, was there a reason that all of the victims were somehow connected to Frank, or was that just a necessary coincidence?
