Assume that all 'visions' in the bible, including Revelation, etc, were actually real and they happened while those people were lucid dreaming or in a lucid state. Assume that if God or angels were to speak to you, that is the way in which they would do it.
You can ask God only 3 questions and 1 proof question. The 3 questions are about anything and the proof question is asking him something so you can verify the answer or the answer will give you absolute proof that it was him you were speaking to and it was not just in your subconscious making him up and the answers. What would you ask?
The reason for this thread....
I've had many lucid dreams. If you have never had one, it's when you become aware you are dreaming and you are shocked because the world is so vivid. Just KNOWING that anything you can do and want will happen, you can do anything. I've recently though how many of those visions they were probably in a lucid state. They had full consciousness yet they were still asleep. I have never thought to try to summon God while in a lucid dream. If it's possible and he did respond and it was not just my subconscious, then I'd need to already have questions ahead of time to ask and a proof question. The proof question is maybe something about a person that nobody knows that I can verify with them on it, or some event that will happen, etc, something that can be confirmed that you would have no way of knowing prior.
I'm curious what you would all ask and what your proof question would be.
