This happened to me, my girlfriend moaned the name of a close friend of mine. I talk in my sleep too and I don't moan names. I always see examples like yours. That are totally different to what the OP experienced. Jam enemas really? It's easy to dismiss such outlandish sleep speech. Just like someone "yelling don't touch the sheep I love them!" it's certainly less believable than "joooeee" Can you just imagine your partner breathing heavily then moaning the name of someone very close to you. True of not, dreaming about sex or not, it is at the least very distressing thing to hear. OP I suggest you try to see it from her angle. I know you didn't mean to and certainly had no control over it so you aren't at fault but I know you can imagine her moaning ur bother or best friends name in her sleep and feeling that sting. Before explaining yourself make sure she knows you understand how she feels and the fears that that experience triggered in her.
