The Lucid Dreamer

I've already read a little bit of The Lucid Dreamer, but I'm really excited about reading the whole thing. It's full of really interesting information about how the brain dreams. What I'm most interested in is distinguishing the difference between the dream world(s) and reality. Is this world just as much a construct of our imaginations as our dreams are? What makes us sense dreams, and why are some senses more accute than others? What facets of the brain affect how we view "reality"?

Starting "On Intelligence"

Well, On Intelligence arrived and I've started reading it. It's not as well-written as The Singularity is Near--not as urgently. But I can tell it's going to be interesting. I want to know if there's any hope for technology expanding humans' consciousness and intelligence. Unless it does this, it's only going to weaken our species (the Singularity scenario seems to partly make up for technology's backfalls by taking our bodies out of the equation and making us super-smart). Unless technology is going to benefit humans and not just surround us, it's not worth it. Please tell me what you think: will it be good for technology to expand our minds vastly (if you're like me and you automatically set up tent in the "technology is bad" camp, try to get rid of that prior notion to answer this question), or will it be destructive to us?
