While Aziz is describing a group of reptiloid subjects and their immediate environment a small light seems to move toward the surface of the screen from behind and wiggles before disappearing. I am sure this is an odd optical artefact perhaps related to the electrostatic (?) technology of the screen. But do have a look at 54:41. I have not seen, or at least not noticed, anything like this before during a Farsight presentation.
You need to look just to the viewer's left of Aziz's sketch. It is very quick but easily visible after you have seen it once. Someone messin with you Aziz?
