of course it's subconcious and therefore cannot be controled. think of having full control though.
With a little training you can actually take that control. It's called "lucid dreaming" and it's the process of taking conscious control of your dreams. I've succeeded once or twice in the past; it's pretty wild. If you've ever had dreams where you can fly unaided or manifest other powers then apparently you're on the right track - that's a form of lucid dreaming.
Look it up on the web. It's fun.
life is just there to help you control it when you die.
That could very well be. It's entirely possible that, to the dying brain, the last moments will appear as some kind of eternal dream. Who knows? Nobody comes back to tell us.
Your beliefs are fine, there's no requirement for you to believe what we want you to believe. Personally I try to avoid believing in things simply because I'm afraid of death. I'm not. (Why fear the inevitable?)
if you work 5 out of 7 days in a week for your entire life... you are only free about 20% of your whole life to do what you want...
Well, nobody makes you work. If you're working, it's because you chose to do that because you felt the benefits of a paycheck outwieghed the lameness of somebody else telling you what to do. Plenty of people have fulfilling careers, I guess. (I haven't met any of them, yet.) So, in a sense, it's still your choice.
