> After all reading a book doesn't give us an experience, its all "just" chemistry too..
I'd disagree there. It's less experience than actually doing something, but more than just getting a chemical flow across the brain. Reading is a weak sort of experience, no?
I was being toungue and cheek. Of course reading a book is an experience, as is taking drugs. And its not just chemical , you might go to the park and have an adventure between two blades of grass or something. Its not like people just drop a tab, close their eyes and lie in bed. I would say in order of strength of experience I would say something like: [Big Adventure without drugs] > [Small adventure with drugs] > [Reading] > [Dreaming]
