Dream Interpretation Help?

I have had this dream only once in my entire life. Well once I went to sleep, and i wasn't under that much stress I'l note. I awoke in a garden, and it was very beautiful, and I walked around in this garden and I kind of knew it was a dream. And this man dressed in white, he came up to me. He was young about 30, and looked very nice and we sat down, I asked him what his name was but he said he did not have one. And I started to feel very good, Physically and Mentally. I felt I was in a God like position, and I could control everything. It was a feeling that I can still remember to this day, It was indescribable, and I asked him what he was doing here in the Garden and he said he was protecting it from Evil. And he explained to me thats why I felt the way I did, because there was absolutely no malevolence in this Garden, and that he did not really have any power at all, but he Evil -Man did, he had the power of the Garden but he could not ever experience its beauty. And he said the Evil-Man is here and it was up in the sky, and ordinary man just like the man in the Garden, he said that I must choose now who to part with and the Man in the sky showed his hand out to me, while the Man in the Garden looked at me, the Man in the sky was telling me that he could show me the secret of the stars (witch I cant interpret) and promised me power over Earth. While the Man in the Garden looked at me and tolled me it was my choice. And then thats all. I don't remember much of the details but this was a life changing experience, and thats why I remember so much of it, because I think about it 24/7. Iv never had any dreams like this one and I would like to see what other people interpret it as, and share any experiences like this one. Thanks guys.
