The other day I had a dream where I was in an intense struggle with someone and was fighting. Then I woke up and found that I had actually hit my girlfriend (not really hard) who was laying right next to me.

And just yesterday, I was dreaming that I was yelling at someone who was picking on my friends, and I yelled "HEY!!!" out loud before waking up, waking up my girlfriend again.

Just wanted to know is this kind of thing normal, and what it is I can do about it?

Thanks
