They can manipulate sleep patterns, induce instantaneous sleep on biotic subjects, induce perpetual insomnia, remove the need to sleep or make someone dreadfully tired all the time.

The user can cause a subject to sleep forever in a comatose-like state and can even determine how deep a sleep is or how long a person or people have been sleeping. They can also force anyone sleeping to wake up regardless of the circumstances.
