Hey, my friend with anxiety has been overthinking a lot lately. She’s worried about her consciousness, she thinks that her consciousness might suddenly go away and a new one will possess her body. Basically, she’d be dead/permanently unconscious while someone possessed her body. Is there a way to disprove it? 
She believes in spirits, so it won’t help to say that it doesn’t exist. She recently learned that the laws of physics don’t apply under Planck’s length (1.61622837 × 10^-35 meters). She thinks that there’s such a tiny particle that is a consciousness can suddenly vanish from existence completely because it’s so small. How do I disprove this?
She’s tried to do it on her own, it’s scientifically proven that things cannot completely vanish from existence. But now she’s found out about Planck’s length and she didn’t have much faith in science in the first place because she’s a very anxious person. 
She’s tried to think of spirits as energy since they (by definition) cannot be made of matter. That doesn’t work now that she’s invented an element that the laws of physics don’t apply to, while they’re completely undetectable. Even with her “energy theory”, it wouldn’t work. She thought that if we switched consciousnesses very often, we’d probably see the energy coming out of a person. But what if the energy is “camouflaged” because we’re already surrounded by lots of energy? And wouldn’t we be able to see energy coming out of a dead person? And what if we’ve found it, but everyone thinks it’s something else?
