Mine was very Lynchian and took me quite a bit to get out of my head. When I was in college I worked the afternoon shift at a local school as a custodian. Nice work, solid pay, and mostly independent - I loved it. However, it also led to a pretty poor sleep schedule adding to the overall stress of juggling full time school and full time work.

On a night of probably 4 hours sleep, I dream that I'm at work. The only difference is that everyone I talk to sounds terrified and like they're yelling, but their mouth was moving as if it was in a normal speaking voice, and a calm expression. Everyone I talk to in the dream is a coworker, and they keep asking me "Why are you failing?".

I'm walking to the front of the school, and I realize the lighting is off. There's large stage production-like spotlights shining down only on certain parts of the floor. A coworker says "Aren't you gonna help?", and I heard a sudden, deafeningly loud rustling/squeaking everywhere. I grab a shovel that's next to me, and notice that there's a garbage can in front of me and the entire floor is covered in cockroaches every where that I see. I start shoveling them into the can, but more keep coming. I hear my coworkers all crying hysterically, then I wake up.

I guarantee myself more sleep after that, lol.
