Alivia can manipulate sleep in a variety of ways. She can induce various states of sleep, from drowsiness to nearly comatose, and can also induce sleep in those who would not rest naturally, such as type one vampires. She can also manipulate dreams similarly to dream manipulation, and communicate with others in their sleep, no matter what the distance between the people. She can view the dreams of others, and see precognitive dreams. Occasionally she can also give herself her own precognitive dreams, without the need to see another person's visions, but she finds doing so draining, and can only maintain it for a little while. Currently, she does this unknowingly. The ability can also be used to induce fatigue or wakefulness, and to trap others in dreams.
