so tonight, i tried a little experiment.
when i walked into the room around 11:30 to put some stuff down, he started mumbling. now, he has been "asleep" for about an hour and a half by this point. not knowing if he was sleeping or not, i said, "hmm?" and he said, "hmm?" back. i giggled a little bit, and crawled on the bed and looked at his face to see if he was awake. he opened his eyes and looked at me for a brief second. okay, so he's awake. NOT!!! i said, "what did you say?" and he mumbled again. snickering, i tried to get him to repeat it. i asked him again, "what?" and he repeated himself, but this time with a more agitated tone of voice. i asked him to repeat it a third time (because i still couldn't understand him), and he very loudly, slowly, and clearly posed his question that he had been "asking me" in his dream. not only that, but he was VERY frustrated with me and he was talking to me like he sometimes does when he's awake. he even moved his hand up and down in a chopping motion like he does to get a point across. i answered him and he said, "ok". i won't share all the details, but based on the question he was asking he was definitely dreaming. we actually had a little "conversation" - me awake, and he asleep!!
i wonder what it means when people talk in their sleep....? off to research and youtube... :)
