Does a host cause disturbance if they are possessed by a celestial and cause damage?
Yes, because the possessor is celestial. Note, this even applies to Shedim who are “convincing” their still-present hosts. While a case could be made for a Shedite “sitting back” and letting the host get along with his job as a car-compactor operator, the Shedite is still the one fundamentally in control. Disturbance will be generated.
