The Fellowship of the Ring
That night they camped on a small eyot close to the western bank. Sam lay rolled in blankets beside Frodo. "I had a funny dream an hour or two before we stopped, Mr. Frodo," he said. "Or maybe it wasn't a dream. Funny it was anyway."
"Well, what was it?" said Frodo, knowing that Sam would not settle down until he had told his tale, whatever it was. "I haven't seen or thought of anything to make me smile since we left Lothlórien."
"It wasn't funny that way, Mr. Frodo. It was queer. All wrong if it wasn't a dream. And you had best hear it. I saw a log with eyes!" (2.9.14-6)
