• He dreamt of a prehistoric man

In "The Call of the Wild," Buck often had visions of a prehistoric man by the campfire.

To find the answer to this question, we need to refer to the novel "The Call of the Wild" by Jack London. Buck is the main character, a dog who undergoes transformations as he adapts to the life of a sled dog during the Klondike Gold Rush in the Yukon.

By the campfire, Buck often had visions of a prehistoric man. These visions represented a primordial call back to his ancestral roots and unleashed his inner instincts, helping him tap into the primal instincts that were buried within him. These visions symbolize Buck's connection to his wild ancestors and foreshadow his ultimate regression into a more primitive state as he embraces the call of the wild.

Therefore, the correct answer is: He dreamt of a prehistoric man.
