Dream interpretation #1

I once had a dream that I was lying down on a beach, and a giant pebble rose from the ground, and started rotating. It got faster and faster until bolts of lightning started shooting out of it. Now, I don’t know what all this means, but I figured it has something to do with the spoiled food I had that night. Michael Faraday envisioned the dynamo in a dream. I pictured diarrhea.
