Duke Zhou dreamed of falling from a height.

Dreaming that you have risen to the sky implies that you have made efforts, but you have no blessing to enjoy it.

Young people dream that they are climbing, which means that they will be promoted step by step from humble position, but there is no more happiness in life.

Dreaming of meeting a god or a friend in the sky means that you will be very painful, and you will gradually overcome it as time goes by.

But you fell from a height, which means you are all right.
