Brian's LSD trips written in the 1991 autobiography

[puni puni]

I'm led to believe that there is a section in the 1991 autobiography which deals with BW's LSD trips and what he had experienced, from seeing his future to dying in a fire. I always thought the "future" trip was a little hokey, but in Love & Mercy, Paul Dano references it in dialogue. Does that mean that, in an indirect way, BW has confirmed that this part of the autobiography was true?
