Explaining brain zaps to pwople who've never felt them

Ok, here's my try:

Imagine your essence, like your actual being or soul or whatever you want to call it, is just traveling along in a linear fashion, existing from one moment to the next as it always has. Now Imagine that your brain gets snagged - the rest of you is still moving forward as always, but your brain gets hooked on something and gets stuck back behind the rest of you. The tautness/tightness/uncomfortable stretching begins to grow and intensify, between your body and mind- until it's stretched as thin and tight as it can handle, and starts buzzing with electricity. Suddenly it SNAPS like a rubber band forward to catch back up with the rest of you- a movement that makes your head and neck throb and makes you want to puke- like being jostled in an old rickety wooden roller coaster going around a bend or steep sudden drop. You close your eyes and brace against the lingering buzzing currents in your head and spend a few minutes trying to overcome the nausea and dizziness, grounding yourself and breathing through it.

You've finally beat it. The nausea subsides, the world rights itself as the spinning slows to a stop...

...and then your brain catches another snag.
