Document Summary
It depends: stevenson (2003) records more than twelve different conceptions of imagination. The capacity to have perception-like experiences in the absence of relevant external stimuli. Sensory imagination depends on internal inputs to sensory systems: mind-wandering/daydreaming. Thinking about things unrelated to your current task. People mind wander about 47% of the time. Even pilots mind wander when they are idle (using heavily automated pilot machinery. Some evidence that mind wandering is related to working memory. When daydreaming is excessive to the point that it leads to adverse effects in daily life. Leads to loss of time and neglect of basic daily functions. Might be triggered by trauma or abuse.

Actual and imagined movements may be distinguished by inhibitory signals sent from other parts of the brain to the motor system.
