In a fantasy experiment, I tried to imagine how that being on the other side may feel about this guy who posted the video.
The being is just rolling reality as usual, when suddenly this guy climbs out from it who seems quite confused and starts asking questions. What to do with this? If this guy goes back to his world and starts to tell everyone about this, then that would "loosen up" his reality and this may jeopardize God's plan with it. Reason: if the world becomes too loose, it won't provide enough resistance for the truth to blossom. Those who come to a realization that it is an illusion won't be able to be immersed in it deeply enough to keep the game going. If they cannot believe it, the forces of polarity will be lessened, therefore there won't be enough power generated (pos/neg -> current) to do the work. Therefore the being tries to tell the human to keep silent about the whole thing. But the guy is very excited, he thinks he got into heaven or what and when he comes back, he cannot help but "yell it from the rooftops" so to speak. We may think he's like Prometheus, who brought (stole) back something for us humans from the world of the Gods, but in reality this may be a bad thing. Perhaps even he would remain silent if he understood the bigger picture.
