Try and get back into your own crumpled body...
From Create Your Own Story
You focus on trying to feel the pulling sensation, behind your eyes, again. You stare at your body long and hard, and strain your vision to the point where you can strain no more. You stop, and look down at your mother's body, again. There must be something that's different with going back to your body, you realize. Rather than straining your eyes on your body, you close them, and concentrate.
You open your eyes, and staring up at you is your mother, confused and terrified. Good, you think. You can get back to your own body.
With this knowledge, you can possess your mother's body, again. Or, you could test out your other abilities on her.
