A capybara wandered through the living room. I stared at it, perplexed. Didn’t capybaras live in the savannahs of South America? What was one doing here, in my house? I suddenly realized, as I looked at the capybara, that I must be in a dream.

To illustrate my point, I focused all my attention on the capybara. I willed it to grow. It grew until it was ten feet long. Then I made it stand on its hind legs and dance.

The sight was ridiculous. I laughed and laughed and laughed.
