In everlost being a skinjacker is a amazing thing. A skinjacker is when you can become another human. As in be come in control of their mind, movements and everything else. The ghost who is a skinjacker is in a coma in real life. Sad but true

Person 2: Ya. She just jumped into that human right there.
