Bird on Willow

"Hollyhock, hollyhock." I pushed the sleeping man next to me, hoping that he would wake up and listen to it with his own ears to confirm whether what I just heard was true or false. Was it my imagination? Is it my imagination? Or is it a strange dream in my sleep? But the man slept like a dead pig. He said "Hmph, hum, hum" a few times from his nostrils, turned over on his side, turned his back to me, and continued to sleep.
