On late autumn night, the disciple woke up crying.

So the master  asked the disciple:

- "Did you have a nightmare?"

- "No"

- "Did you have a sad dream?"

"No" said the disciple. "I had a sweet dream."

- "Then why are you crying so sadly?"

The disciple answered quietly while wiping his tears...

-"Because the dream I had can't come true."
