My mom has told me that when I was a child she would frequently come into my room when I was asleep and that I would have full conversations with her (even with my eyes open) and I would never remember these conversations.
I have occasionally woken myself up talking as well. It's pretty funny.
My husband has never experienced this phenomenon. He is a very heavy sleeper and wouldn't notice if the world tumbled down. But today, he got to experience my "sleep talking". I took a nap this afternoon and he got to wake me up. Apparently, this is how the conversation went:
Anthony: Hey babe, you should probably wake up. The baby is in her swing.
Me: Who's on my lap?
Me: Is the baby on my lap?
Anthony: No, she is in the swing.
Me: We have two babies.
Anthony: No we don't, we have one baby.
Me: No! We have two babies, they are both bottle fed.
At this point he started laughing. I got really mad at him for laughing at me.
Me: Why are you laughing? Do you want me to punch you in the face?
Anthony: I am going to take a shower.
He walked out of the room at this point and a few minutes later I actually got up. He then repeated this conversation to me at the dinner table while I was feeding the baby and in my hormonal state I laughed and cried at the same time.
I think I am glad we don't have two babies. Anthony is not sure that I was asleep. He said my eyes were open. I told him to ask my mom about my sleep talking. :)
