I'm really curious as to the title of the book Stan Lee was reading in his cameo appearance in Doctor Strange. Is was relevant to the story, and I tried to make a mental note of it, but that mental note was totally lost in the crazy mind trip that followed.
Doors of perception by Aldous Huxley.
Its a well known book about "expanding mind" using mescaline and other halucinogenic drugs, which author describes as almost religous in their nature. This book became some sort of bible in the 60s, Jim Morrison called his band after this book.
It is quite fitting, since we can see it during pretty "tripping" scene
