Our psyches, like nature, need periods of rest and regeneration. Some overly positive psychological models have no place for the dips in mood or energy that are a normal part of life and which can be seen in the cycles of nature. We have to learn to not fear those moments when we do not feel completely in control, or when lose our sense of direction for a while.

There are moments in human life when a new page is turned. New interests and tendencies appear which have hitherto received no attention, or there is a sudden change of personality. During the incubation period of such a change we can often observe a loss of conscious energy: the new development has drawn off the energy it needs from consciousness. This lowering of energy can be seen most clearly …in the empty stillness which precedes creative work.

Jung, The Psychology of the Transference, CW 16.
