Dream Control

Used mostly in the context of lucid dreaming, Dream Control refers to the ability of the dreamer to exert his/her will towards the dream, changing characteristics of the scenario and specific elements. Dream Control can be expressed in many different ways, though the amount of control ultimately relies on the dreamer's expectations.

From the Dream Control Tutorial:
If, for example, the intention is to fly, such result can be achieved by simply jumping and expecting to stay in the air. Flying could also be achieved by expecting wings to show up on the dreamer's back, or even that a small cloud appears to carry the dreamer through the skies. Other elements of "control" can be achieved in the same manner.

Simplest form: The desire of the dreamer influences the content and creates the ability to control the dream.
