I confess that I am a "science guy" at heart - I like to have proof of
most things.
That is not to say that I don't find discussion of unproven (non-provable?) subjects fascinating, and there are plenty of instances where I would love to be able to experience something that I cannot think of any way to prove.
Steve's post, however, uses lucid dreaming as an example. Now this is something that I found fascinating when I first heard of it (on this blog) and I have since learned, with a lot of patience, to accomplish (although not very often). So this is rather a poor example of something which is non-provable.
I am torn as to whether to believe that all things possible are also provable. I would like to think so, and that we have not yet found the proof for some experiences, but if
Gödel's imcompleteness theorum can be extended outside the realm of mathematics then perhaps there are some things that we cannot prove.
As for objective reality - for me it's a nice thought but even if it is true I don't think I could be objective enough to experience it. For the moment I'll stick with my attempts at lucid dreaming
Cheers
