Nana is trying to catch unseen moving objects.

Nana may be detecting small insects or other tiny flying creatures that are attracted to the light in my bedroom.
The movement I am seeing under the camera flash could be small insects or dust mites that are being illuminated briefly by the camera flash. These tiny organisms are often hard for the human eye to see clearly, but can be detected by a cat's more sensitive vision.
