Auditory hallucinations are very common - and you "hear" them like somebody is really there in the room with you. They're pretty neat. The most common one is where somebody says your name behind you, you turn around and there's nobody there.
From what little is known about this, there's a center in your brain which produces these "voices" - and of course in the schizophrenic this is truly active. But everybody gets these - not only crazy people. Mostly we keep control of our conscious mind - but where there's diversions like a lot of noise in a factory or a waterfall, it confuses the mind and the voices will come through.
This is probably the reason why "high places" were thought to be occupied by "god" in early religions - because the wind blew the trees causing a cascade of white noise which then allow these "voices" through. In Greek myth, "sacred" groves and waterfalls were often thought to be occupied by sprites or spirits or gods. This might be the reason.
This phenomenon seems to be a younger person's thing. As the brain ages, this phenomenon doesn't happen nearly as much. Spooky video has it's own sort of odd stimulation of the mind - these sorts of spook shows form connections with repressed material in your mind - stuff out of your past.
That's why people flock to spooky movies. They LOVE to have this experience of being "frightened" - sort of like the "running of the bulls" - people like to flirt with "danger and fear". Anyway, your spooky videos probably allow your mind to form these connections with your unconscious "ghosts" allowing the voices through.
It would be fun to know what the voices tell you.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
