Do these visions of the future seem believable to you ?

I'm suspicious of Dr. Goldberg's claims when he says you may not experience this future if you're on a different frequency. Doesn't that invalidate the vision? If my vision is different, he can just claim I'm on a different frequency. Also, he must provide proof that these "thousands" of hypnotic sessions actually took place and name everyone he hypnotized. I honestly don't believe any of this.
