Illusion

A cat, a-warmed atop a car,
And then asleep, might travel far;
And peering open one dim eye,
Note the flora whizzing by;
But yielding to its eyelid closure,
Resume at once its former dozure.
At last at home, adventure done,
Returning where it had begun,
Our cat on waking might look down,
And on its face a puzzled frown,
Ponder all but fail to deem:
Was that real? Or just a dream?
