They are on youtube of course.
They are easy to find.
Just look up terence mckenna or graham hancock, and quite possibly add the word schizophrenia to your search.
It's that easy.

The graham hancock interviews really touched me when he started talking about half animal half human beings visiting humans well, since we've existed. Because that happened to me.

So, just go to youtube and do a little search for the terence mckenna and graham hancock interviews on ye olde schizophrenia and things, they are very intelligent people, who knows if their hearts are actually in the right place though.
