Your violent death usually triggers the first switch.
Just before your life ebbs away, your skin happens to touch another human being - and in an instant, your consciousness transfers completely to the person you touched.
From that moment on, you can leap from body to body with a touch of the skin. You can remain for a minute, an hour, a lifetime, and after you leave, the host has no memory of the time you were there.
