The best thing to do is to try Lucid Dreaming. Oh, it is wondrous. Is recommend a WBTB technique, meaning wake-back-to-bed, or FILD, for beginners, promised with great results.
The reason I suggest this is because Lucid Dreaming is similar to AP, but also can induce sleep paralysis, and teaches you to sleep, but only physically, and to stay mentally aware and awake. You can control almost anything in your lucid dreams once you come to terms with your dreaming state. You can almost make it astral projection, but simply a perception Or a manifestation, but nothing more.
You will need to do Reality Checks during your conscious hours, simply hiding your breath and looking at your hand and counting your fingers, when you experience any emotions such as frustration, fear, happiness, anger, excitement, and depression, all common within dreams. This habit will eventually carry into your dreams, and you preform a reality check within, and you will realize you are dreaming. Then you are enabled god-like manipulation of your dream.
