Well, after reading your profile, I would say you have some learning to do. One, do not learn from tv shows nor movies. They are entertainment only, and will only confuse fantasy from reality. That said, I think you're flying dreams are cool. Represent a freedom of a kind. Maybe a longing to be free from something, or wanting to fly towards something; possibly the magick interest. Now I'm not sure about the nightmares. I would need more info on them.
You are wanting to learn, so let's start. Go to the forums/ general info section, and read Starting Out and Basics Expanded. They are good reads for the beginner. Good luck, and feel free to mail me. Blessed Be...
