Weird Voice Coming From Living Room?

are you absolutely sure that you were awake? sometimes people think that they are when in actuality they are not awake or fully awake and they are still dreaming. i have had this happen to me. i was checked out and found to be still sleeping and the voice i heard was still part of my dream. it isn't all that uncommon and can be extremely scary. since it has not happened again i would not worry about it.
