That information given to Strieber by the mystery man formed the basis of a book co-written in 2000 with legendary radio talk show personality Art Bell, “The Coming Global Superstorm,” which evolved into the 2004 apocalyptic film “The Day After Tomorrow.” (Huffington post)
Apparently, Strieber was visited by a stranger one night in a hotel. Who told he all kinds of strange and wondrous things from the dangers of artificial intelligence to the concept of Multiple Universes. Now I’ve got a friend like that, and when he’s drunk he does go on … but apparently Strieber
“… has never fully concluded who or what his 1998 visitor was. As hard as he tried to find the unusual man, Strieber never saw him again after that night. “It’s possible that this was no ordinary human being.”
In other words it was an alien!
