Is it normal to do this in my sleep?

So I come home earlier this mornin' about half 7, tired as hell from a night shift, soon as my head hits the pillow, i'm out cold. But then I dream (or so i thought) about waking up, and taking a piss in one of my drawers full of my t-shirts, for some reason i felt like i needed to do this, and go back to bed. So I wake up (for real) and out of curiousity of recalling the dream i had, check my drawer, and feel my t shirts, and they're really damp. I've never had any history of this happening to me before, i have sleepwalked but not being conscious of it and unable to control what i was doing, I even remember thinking (woah, i don't wanna get the tshirts my girlfriend got me wet, just these white ones). I do have the weirdest dreams, just about the most regular shit you might do, which always confuses me in the morning as to whether they happened. Anyone ever have this before? Am i losing my mind?
