A "plate of shrimp" has become a catchphrase that is used to represent certain types of events one experiences throughout the day involving the odd coincidences in life that seem too random to just be chance, suggesting some kind of mysterious force just under the surface of human reality and perception.
The only real evidence of a plate of shrimp occurring are the odd, strange, and weird coincidences that seem to creep up throughout the day, from very mundane details to very pivotal realizations.
It also seems that the more one recognizes these events and appreciates them, the more they seem to happen, and, perhaps, the more meaningful they become.

Sure the theists will immediately describe it as God's will etc ... which is fine for them, but what about the rest of us who don't really put all of their eggs in that basket, those of us who are interested in rational, analytical examination of the human experience.

How does a rational, analytical person describe these events? Is it quantum physics working its patterns on us, or vice versa? Is it a glimpse into an alternate reality? Or is it just a deeper glimpse into our current reality. Do these occurrences have meaning, or are they just odd random coincidences without any meaning?

The Movie "Repo Man" is where the catchphrase was coined ...
From "Repo Man"

"A lot o' people don't realize what's really going on. They view life as a bunch o' unconnected incidents 'n things. They don't realize that there's this, like, lattice o' coincidence that lays on top o' everything. Give you an example; show you what I mean: suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconsciousness."

I personally have some extraordinary stories of these cosmic coincidences. And upon closer examination I bet you do too! I am really interested in hearing your stories, and sharing mine.

So I'll post some of my stories here, and you can post yours too.
