Explanation: The person on the right exhibits a strange doubling effect with their body, as if multiple limbs are temporarily attached to them. This phantom-like mirroring creates the illusion of multiple arms and legs, which appear to merge back into the body and then reappear sporadically, as if the person is momentarily transforming into a multi-limbed figure before returning to normal, generating a disorienting visual experience.
