Is it normal to go in to tunnel vision?

The sun slowly completes its sunrise illuminating the restaurant. In one increment, the striking mechanism hits 12. The clock starts to spin out of control.

Lines stretch out the door way as cars twist around the restaurant. Screens fill up with orders, multiple sodas pop out the conveyor, burgers slide and begin to pile up at the end as orders are being made faster than they can cook it. Today is understaffed with an incompetent manager causing impatient angry customers, provoking the phenomenon that is about to materialize.

All of a sudden everything gradually goes in to slow motion. I enter tunnel vision, a low monotone sound creeps in to my ears, as voices slur, looking left to right causes trails behind the objects and people, intense rays of lights hit my eyes. I start to squint as my lower eye lids bag up. All of a sudden I zoom in to the end of the circular tunnel, eyes focus, and my manager is like: are you alright? I wave my head quickly back and forth like a wet dog, causing my cheeks to quiver and snapped out of it for a second wind, syncing myself back to reality and nodded my head in reply.

In a flash, customers zoom in and out of the doors, in an accelerated motion with predictable routes, leaving streaks of shoe prints behind for me to mop.

I finish my shift and jump in to my car, shove the keys in the ignition, twist, vroom, reverse and step on the accelerator in relief that my shift is over and I’m headed home as the restaurant smoothly shrinks in to the horizon on my rear view mirror.
