Well, I tend to agree... They have a lot of logical connections in common, not experiential. The experiences are different but the conclusions are similar.
For example, if you don't trust the dream and start pushing toward a certain goal, things around you totally screw up. You wanna see your dad in the dream but all of a sudden you end up in Australia (that's dream reality, totally illogical) and you're mad cause you couldn't see your dad. If you were just enjoying the trip to Australia, everything would've been fine. Just go with the flow, and know that life / the dream / Spice ALWAYS surprises you.
You have to trust the dream, if you keep trying to get somewhere or achieve something very specific (like getting laid, hehe), you'll probably end up losing your lucidity.
When you are lucid, there is no fear. Letting go of fear is key to both experiences.
Also, every thought becomes real in a matter of seconds in both worlds. How you think of things is how they are.
