According to my boyfriend I have this and had it for quite some time. Somniloquy is the term used to describe people who talk in their sleep. When it is brought to my attention I am usually just curious about what I said. From what I understand, more often than not I can not be understood when I do it. This leaves Snookums to go "huh" wanting me to repeat myself and me not respond. Recently I apparently wanted to talk about music during my slumber, but the conversation didn't remain as clear on my end as the verbal exchange went on. *shrug*
So weird! What if one day I admit to killing Roger Rabbit in my sleep??? LOL! I joke, but it does scare me that I have no control over what I may say in my sleep and when I wake up I'd have no clue I said anything!
I've been reading different sites that talk about somniloquy and I think mine is harmless and not a sign of a more serious medical issue. For that I am happy.
