My brother finally contacted me about the weird e-mails. He knows the guy but hasn't seen him for over a decade. He wrote to him and the response he got is kind of perfect. Apparently a few days ago, this guy took a psychedelic substance called DMT - at the peak of it, he received a vision to contact me. I had to remember that it's 2015, not 1967. Oracle indeed. He won't be e-mailing again.
