I dreamt that I was spending some time with an Amazonian tribe that knew a great deal about electricity. Although their tools were rather primitive, many members of the tribe could use it for all sorts of purposes. Their knowledge went far back, too. I do not remember any details, but electricity was very useful in dealing with dangerous animals. I remember watching a man working on a contraption made of smooth wooden rods when a jaguar started approaching him stealthily through the lush foliage. The man was small and wore an enormous straw hat. It was clear he was aware of the slinking animal, but he did not look toward it at all. When it was quite close, he pointed one of the rods at the jaguar. The animal yelped, jumped to the side, and then trotted back into the woods. It was obvious it got an electric shock. The man continued doing whatever he was doing without even looking after his detractor. I tried to remember more of the dream when I woke up, but to no avail. The tribe I was visiting knew a lot about electricity, but their knowledge was well beyond me.
