Dune occupies such a weird spot in my brain, it's like a wedge rubbing up against whatever meat gives people religious experiences or something. I read the first book when I was 9 and I swear it made me feel what I eventually came to know was high as fuck. I have not known anything quite like that specific feeling in my life regardless of any inputs, chemical or otherwise.
As a result, I often have a very soft spot for other forms of Dune media including the movies and even the sci fi channel miniseries. If only because on some level they all remind me of the book that somehow got me royally fucked up when I was a kid. I'm looking forward to Dune 3: Where's My Gom Jabbar?
