My aunt certainly seems to think so 
I have a problem grinding/gnashing my teeth in my sleep. Unfortunately this leads to vivid dreaming episodes of chewing mouthfuls of broken glass.
Not really fun.
A few months ago, I had a dream that I was at a get-together, and had just met this cute blonde girl who spoke Chinese (I’m currently studying Mandarin Chinese full-time). We start chatting in Chinese that even in the dream I can tell is badly broken, for some reason we start making out, and just when it is about to get interesting, my alarm goes off.
My room mate tells me my first words that morning were “I’m gonna set fire to that fucking clock.”
I sleepwalk quite often and have the tail end of dreams incorporated into the real world, where I’m still asleep but also awake.
As an example, this lead to waking up one summer night, ceiling fan going, and seeing (actually SEEING to me) a sock floating at the ceiling, held aloft by the fan circulation. I stared and watched it move. I finally noticed, though, that it was a turquoise argyle sock. I don’t have a turquoise argyle sock, my MOM does. My mom couldn’t be in my boyfriend’s apartment, so when I figured that out, the sock slooooooooooooowly faded and I couldn’t see it anymore. There was no waking up after the sock disappeared; I was already awake, just not 100%.
People freak out when I explain dreams like that. 
Used to have dreams where I couldn’t tell if I was dreaming or not, so I would look around. If the door was on the left and the window on the right I was awake, If not, I was dreaming.
The funniest incedent was when I was lying there looking at this giant cat tree in my bedroom. The cat tree morohed into a person, who then reached out and grabbed me. I woke up with a start clutching my thigh. Friend told me she can see the headlines now, ‘Man found strangled in Fremont with his hands around his neck’.
