It sounds to me like what you've done is come up with a list of goals for your own life. It sounds like you want a possession spell so you can live in your dream world while some other entity possesses your body. That's not the way to make your dreams come true. Here's a few tips:
1. Start mediating, if you are not already. This will allow you to build up your energy and help you learn to control it.
2. Look at all the things you love about your fictional creation, list them from most realist to least realist. Make these your goals.
3. Start focusing your magick on making these goal happen. You should use the law of attraction, but some elbow grease may be required as well.
My kids have all memorized the 3 rules of magick: Magick works from the inside out (not the other way around), if you take control of what goes on inside your head you can take control of what goes on outside of it, and the only way to take control of what goes on inside your head is to practice.
It sounds like you've done a good job of taking control of what goes on inside your head. Now it's time to work a little magick and pull that into the real world by making yourself the person you dream of becoming, rather than letting something else become you.
Just remember what I call the fourth rule: you are always where you should be. Don't get frustrated if the journey doesn't take you right where you want it to, as it should take you where you need to go, most of the time, before you get to your true destination.
Best of luck :)
