Can Rh negatives be hypnotized?

I have just now remembered the claim that Rh negatives cannot be hypnotized. What is hypnotism? I am sharing some thoughts in the video above, but there are a few things I have to also bring up: This video is actually where I was alerted to it and mainly because Andrew Huberman doesn’t feel like a charlatan to me. He seems legit and also mentions there are people who cannot be hypnotized. I can see a dream state induced by various methods including imagery, clocks and such to overwhelm the brain and tiring subjects into entering such state. Is it harder to hypnotize an Rh negative? My answer is “yes”. Is it impossible? Possibly.
