Really bad dreams

I took a nap before work last night. I had a dream I was late to work. I wake up and look at the clock and it says 6 o’ clock. I can see it is still light out and think it is 6am and I slept through my shift. I pinch myself to make sure I am not still dreaming. I look at my phone and finally realise it is 6pm. So I went back to my original plan, go to the laundromat and wash some heavy blankets, then go to work.
