I think I might be interested in an entity taking over for me, but nothing low like parasites, I’m more interested in demons in such as the Goetic Demons because they are highly intelligent and experienced. I don’t mind if they wish to “take hold of my vehicle’s steering wheel,” if you catch my drift.
build a solid relationship with them then see if they are willing to! For them possession is intimate thing so most wouldn’t just possess you without knowing you! Start with invocations to prepare your self and build from there!
Working with them is great, but a possession is a very intimate thing.
