I would admire you for your dedication, but it seems like that wasn't under your control anyways. It seems like you experienced a lucid dream from what you're telling us (dreaming until 5pm, meeting people and remembering the dialogue, and making choices). If you're very happy with what you've written, I recommend trying to lucid dream more. Of course, make sure you eat enough and maintain your body because you have better dreams when your body is healthy I assume. Salvador Dali used to purposefully lucid dream to create his artworks, so I would recommend you go for it!
I would try lucid dreaming, but most of the time I'm way too tired so I don't think I've dreamed for a while (well, I probably have according to science, but I haven't remembered myself dreaming for a while now) + the only time I can recall myself having a lucid dream, I had been kidnapped by an old woman who would not let me out of her basement (like a Rapunzel story). She was really nice to me, but as soon as I realised I was dreaming, and thus was able to control my dream, the only option that seemed available to me for escape was to kill her. So... maybe I'll try lucid dreaming another day.
As for the story being too gory, other people have already addressed that ^_^
