In lucid dreaming I managed to speak with some "guides"(probably just part of my subconcious though) and even then I really never learned anything really. They never made any sense.
See, this is what I am talking about, that people equate Dreaming with Materialism -- that Dreams are inevitably from the Subconscious and therefore contain absolutely no objective or even subjective relevance.
Oh, and regarding how easy it is to understand Oracles, Prophecies or any Divine Revelation. One is reminded of the Riddle of the Sphinx, or the Curse of Cassandra, or so many legends of the Oracle of Delphi where Princes and Generals came to ruin by 'interpretting' these ambiguous and paradoxical messages in exactly the wrong way.
Anything Truly Spiritual has an element of Paradox, not in the sense of contradiction, but in the sense of Inclusiveness, of containing both equal amounts of Yin and Yang.
One-sidedness is easy to understand. But Balance and Equilibruium can be complicated.
I have had Messages in my dreams that I have had to think about for months at a time, even years. And I am Smart.
So it means little when you wake up from a Dream and the first words out of your mouth are that your Dream Guides are stupid because YOU don't understand THEM.
I once had a dream that I was in Heaven, and suddenly there was an uproar of excitement in the crowd, of great enthusiasm because the "Oracle and Greatest Poetress" was about to come by. And then there she was, she was singing and rhyming in what at first sounded like pure nonsense, but then her words left an afterglow of residual meaning that amazed and amused and astounded me.
In Heaven they understand these Guides, the ones that you call stupid figments of your 'subconscous mind'.
The impotence and futility of Materialism hard at work...
