I am hearing in my dreams.
lol so I am! My whole life has always been full of dreams, I go to bed each night looking forward to whatever dream my imagination will dredge up. I remember nearly all the dreams I've had, all the way back to when I was a young kid. Most dreams are familiar, a repeat of scenes, people (sometimes tv actors are in them too lol) so when I go back to a familiar scene, I know what's going to happen, so I try to change things each time to prevent any bad things that happen to me in my dreams.
My dreams are always weird... and sometimes I can hear 'real' conversations, however people in my dreams always understand me, as I am articulate, fluent in each language that I chose to speak (even though I don't know a particular language, I simply pretend to speak it by making up words) and also, oddly, my dreams are Technicoloured!
Some of my friends (hearing and deaf) when asked, would tell me they really can't remember their dreams as they don't really think about it, but that when they do remember their dreams, it's usually in plain colour (black white, fuzzy, etc)
However I can also be conscious sometimes that I am dreaming, and if I don't want to be in a particular nasty/bad dream situation (nightmare) I can wake myself up by closing my eyes in my dream.
