When you "heard" him talking, he may have been talking in his sleep - which would have nothing at all to do with you. My BF does that from time to time and I've had to learn that he's NOT talking to me.

If you're really stressing, then that could bring on hallucinations. I've had THAT happen before! Audio, video, both...

I understand about your nightmare - that's the only one I ever have. No Freddy Kreuger stuff. Always always always nightmares about my partner leaving me. Makes sense - that's my worst fear! And they're really vivid dreams. More real than real sometimes. I really have to keep my mind on the fact IT WAS A DREAM!!! 'cause I wake up crying or yelling or angry or scared and my poor BF has no clue what I'm so upset about. Dreams aren't real. Dreams aren't real. Dreams aren't real.
