I think dreams are an opportunity to experience other lives right here right now. I think you'd be foolish not to try to learn something from your dreams, but don't take it seriously in the sense that everything in your dream is going to happen in your regular life or something like that, I've never heard of any teaching of the buddha teaching dreams are nonsense, is their one???
18 years ago I made one of the most important decisions of my life and entered a local Cambodian Buddhist Temple as a temple boy and, for only 3 weeks, an actual Therevada Buddhist monk. I am not a scholar, great meditator, or authority on Buddhism, but Buddhism is something I love from the Bottom of my heart. It has taught me sobriety, morality, peace, and very importantly that my suffering is optional, and doesn't have to run my life. I hope to give back what little I can to the Buddhist community that has so generously given me so much, sincerely former monk John
