I used to think that it was important to deepen and correct our ideas about dream phenomena, because the limitations of our ideas are limiting our experiences. I still think that's true. However, now I see that there is another consideration that I was missing which might be more important. An idea or a framework of ideas is a kind of prison. Learning to think with more independence is more important than improving the prison. If one of us were to somehow write an awesome book on astral projection, for example, people would believe in it religiously, and they'd reason from that belief, without being able to separate their own experience from the thoughts they have faith in. Of course books and ideas are helpful, but I think this consideration is a big part of what holds us back. We really need more progress on strength of critical thinking before we need much more theoretical or experiential understanding.
