Delia Ryans has the ability to mentally project her own consciousness remotely into the minds of sleeping individuals and manipulate their dreaming minds. Delia’s limitations on distance that she may travel in dreams is limited to approximately 200 miles and any mind within this radius is privy to her access. She can, however, overcome this limitation by using a method of hopscotching between consciousnesses. While in a sleeping mind, she can make the suggestion to a person or animal to travel and upon their awakening, can travel with them. Using this method, she has been able to travel across the United States and into Canada, though fear of losing herself (again), has stopped her from going overseas. Being in the mind of a sleeping individual is a simple task and she may do so and be as rested as if she had a full night's sleep, regardless of the time spent in this individual's mind.
Once in a dreaming mind, Delia is able to control and shape it to her desires. She can change a nightmare to a peaceful dream, she can change how she is perceived in the dream. Delia is able to will herself into a sleeping state by calming her mind and controlling her breathing, much like meditation. In a mind, she can forth another awake either violently or gradually. Using hypnotic suggestion, she is able to aid people in tasks like kicking drug habits, mental addictions, and even some forms of mental illnesses such as depression, paranoia, and catatonia. Opposite to her gift of healing, Delia is also able to cause the same mental illnesses that she can cure, though it taxes her greatly both physically and mentally. For instance, in the case of causing catatonia, she will suffer insomnia or be unable to dream for up to two weeks.
Delia is able to puppet the bodies of two types of people, those currently on refrain and those who are in a permanent state of coma. When people are in this state, she can cause them to slow moving action, such as the shamble of a zombie and movements of limited dexterity. Doing so taxes her greatly and she will wake up unrested. As with causing mental illness, too much of this will render her sleep deprived and actually leave her vulnerable and unable to defend herself mentally while both awake and asleep.
Delia is able to scan the most recent memories of the mind she is dreaming, this was originally intended to allow her to make something of a map of the real world while she was lost and though her travel methods have evolved, this particular skill has not. The limit of this ability is, at most, the thoughts of her victim during the hour before they fell asleep. It is not full memory analysis and it is difficult for Delia to detect whether what she sees is truth or just a dream, because of the nature of dreams themselves. Because of this, people who have been trained against telepaths and telepaths themselves will find it very easy to lie to Delia in their dream state.
Delia's ability to enter the minds of other psychics or those with mental training to resist psychic intrusion is limited. True telepaths can entirely block out Delia and if they become aware of the intrusion in their dreams, could even trap her (much how Maury trapped Molly in Season 2 of Heroes) within their mind or her own. The majority of interaction with telepaths would be on a case-by-case basis on how she interacts with their abilities.
Lastly, If a person wakes up without warning or she remains after her dreamer wakes up, Delia's consciousness will be trapped, frozen, inside of them. This renders her body in a coma-like state with only autonomous function. She cannot be freed until the person she is trapped inside falls asleep again. In this state, Delia is undetectable except by telepath.
