He is involved with Ziva Dynamics, a VR company, through which he has experienced nightmarish footage involving strange creatures that creep up on the user.
Its so real: its the stuff of nightmares Weve got to be really careful because you could put somebody into a psychosis, he said.

Shatner is brilliant at this kind of stuff. Remember Priceline. He made a small fortune on Priceline.
Shatner has an eye for up and coming tech/ideas/companies. And he is excellent at create buzz about those things.
Here, Shatner is introducing the world to Ziva Dynamics and Ziva is pretty dynamic.
As far as I can tell, Shatner is referring to Ziva's work in building character animations by starting with accurate skeletal structure and then adding, in sequence, muscle, fascia, fat, skin, and hair. This animation is accurate right down to the way the skin and fat and muscle react to elemental force that are present in their environment (like wind and gravity).
Here are some very short videos that illustrate how Ziva's work produces incredibly lifelike animated creatures:
