I Had a Dream

By Emanuel Derman

In this article on nightmares in the WSJ, there is the following paragraph:

Modern psychiatrists, led by Allan Hobson of Harvard Medical School, believe dreams are electrical pulses from the brain stem randomly bombarding the center of the brain where visual memories are stored, creating kaleidoscopes of images around which the brain concocts stories.

Here is the same paragraph, with one word changed:

Modern psychiatrists, led by Allan Hobson of Harvard Medical School, believe thoughts are electrical pulses from the brain stem randomly bombarding the center of the brain where visual memories are stored, creating kaleidoscopes of images around which the brain concocts stories.

Does that count as an explanation?
