Yep, I spoke while having an almost LD. It was late at night and I was having a dream, I wasnt aware that I was dreaming, but I had full control, all I had to do was an RC, but, I forgot XP. Anyways, I decided to scream in the middle of nowhere. Apparently I screamed in real life, it woke my family up, and at the end, I woke up, because it was loud. I was fully asleep, dreaming, it was a REALLY cool expierince. Or however you spell that.
I thought nobody would care =P.
I want to do that, but my family would get so pissed off… 
I used to talk in my sleep when I was alot younger. Awhile ago I remember my sister telling me I was talking in my sleep, and right when she told me what I said, I remembered that part of my dream and saying what she had told me. It was a weird feeling of deja vu. But I have never yelled in my dreams, or so I dont think so?!?!
