This sounds so interesting! There’s a book by Frank Young called Spirit Thought Magic, that discusses this (near the end though). I used the techniques (sorry, forgot it now; but it comprises of just astral travelling into their body, like you can with their mind), and did it to my uncle’s ex wife, so basically was hiding their kids from us. I messed her up, and instilled thoughts like she felt like an awful person for doing what she’s doing. Next thing I knew, the kids came earlier than she said they would. She also let them stay for 3 weeks, which is longer than she normally would.
Sometimes I think about that, and wonder if I could go into her body and shut it down. I went into her body and my skin & ovaries started feeling weird, suddenly. Then I found out she had some severe Ovary cancer and skin issues. I would be careful of that too, because when you leave their body, you may take it back with you.
