I never 'hear' voices in dreams, characters 'talk' but there isn't sound as I would interpret when I was awake,
but I had a dream with a character's voice from a tv show, he was talking japanese and there was subtitles I think,
may have watched too much anime e.e
I also don't dream about myself a very lot, sometimes the dream may start with me but they all become characters,
I wonder if that's because my brain is working different then when I was little because how many years I'm been generating storys in my head.
Am curious about what you guys dream about : o
