More powerful spectral manifestations have the ability not only to levitate objects, but also to imbue them with a temporary sense of life. This is usually done to effigies and statues with discernible body parts, but more exotic variants have occurred, depending on the proclivities of the animator. These creations are usually easy to disrupt and are only a serious threat in large quantities.
Gargoyles are sort of a standard example of a psychokinetic animation candidate, as they already have a significant amount of emotional resonance, a generally unsettling appearance, and they're made of durable stone. Stone is hardly resilient when faced with positronic disruption, however.
Their stone skin resists many ghostbusting devices, including most of the experimental gear you're trying out. Liberal application of the Boson Dart is the best way to reduce these to rubble.
The art page can be found in Central Park Cemetery, during the "No Rest..." section. It is hidden inside a monument near a Gargoyle attack.
