The Mirror Book

Part of the book I am reading is showing me some rituals and simple practices that will help me become more in tuned with the craft. The mirror book is simply a place where to write my daily activities revolving the Wicca faith. What I have been doing already just not privately, which I don't mind. I also have been working on visualization, which I cannot do even a little. I don't understand it, am I supposed to actually see something as if my eyes were open (like a dream), or am I just supposed to imagine I am seeing it. In the book it says to just close your eyes and relax and pictures will just start to appear. Well they don't . So I have to figure this out, and no one seems to know, and I do not know anyone who actually practices Wicca. The book also says to try and become closer with the God and Goddess by focusing on the powers of the sun and moon. But I feel when I go outside and stare at the sky my parents will think I am crazy. So I do it when They are not home like this morning, I meditated and asked the God to help me become focused and feel his powers and the sun behind the clouds came out and I could feel the warmth all over my body (but that is what the sun does so is it power or just the UV waves from the sun?). I also did some stretches to become more relaxed and it kinda helped. That's all I have been working on, but there is a sabot coming up on 4/31 called Beltane I want to be ready be then but we will see.
