So what is a thought?
Quick answer. One function of the brain.
After reading bobcat's post about thought. I'm thinking my thought about the post is probably best described by bobcat in his post.
They seem to be merely mental representations, or psychological presents that bombard us from all directions, and even when we sleep.
Sometimes they are conscious choices, but many times they aren't. About half of the time our thoughts veer off from what's going on around us.
