Query: my brain is fried

Ok, i must admit, so i didn't exist during the 60's-70's massive drug taking psychedelic hippie era. But, i still enjoyed this book. I don't see how anyone couldn't. My mind tumbled, flipped and turned and split in half right down the middle. Why aren't more books like this? Why didn't anybody suggest this book to me sooner? I had to go searching to the other sides of the universe for this author.There aren't any adjectives left to descirbe PKD other than...cool.
