The All-Night Dream Conundrum

I had a dream that there was someone who rewarded people who answered his riddles correctly. He apparently had the reputation of telling easy riddles and giving grand rewards. Unfortunately, before my dream began, this person acquired a book full of harder riddles.

And it was just my luck that an extremely difficult riddle was given for me to answer.

I couldn't answer it.

Therefore, I wouldn't know what the prize was.

That plagued me the entire night, as I was searching for either the answer to the unanswerable, or for the prize itself.

Such is dreamland. Fortunately, the next night was a night of comedy, and I felt like I was laughing the entire night.
