Andrea can put others to sleep at will. She can do this by either touching the person, or by using other means such as yawning or simply selecting the individual in her mind. She consciously chooses who will go to sleep, and that person will do so either gradually or immediately, which again is selected. Once the person is asleep she cannot control how long they will sleep for, however it usually lasts at least half an hour. This form of sleep would not be suitable for a person to experience precognitive dreams if they possess the relevant ability, since the sleep is unnatural.
