Hi Carrie .
Yess im doing it all the time having full on conversations when im sleeping.
my boyfriend said he is startled im going on for ages reall talking even shouting somtimes......it worried me.
my mother has seen me loads of times worried somthing was wrong with me in the next room she came in to hear me taking a job interview talking asif i was awake.
yes i found a cause of it over thinking or worrying its like your dreams when you constantly think of someone or somthing you dream it.
but some people talk about it in there sleep.
how long do you do this for carrie?
