I dont feel like explaining everything..i recommend reading some posts made by Serinanth and he is somebody you could learn alot from.
As you will realise control is not the most important(and impossible) where a dream is not a dream, but another reality

You consider yourself powerfull, because you create things in your dreams to your desire. But having everything you desire is not good, and its not good either to be able to have it. Things you need will come to you when you are in need of them. I could have LD and practise ultimate control, but I dont even want ultimate control. I think if you would fall/go as deep..as to the point you open yourself to the other reality and even begin to understand that other world you will not have control anymore, or have need for it.

But of course, not everybody believes in the theory of the two realities. Not everybody respects completely what is out there. Some believe in dream characters and ultimate control of that what is up your head, some do not. I do not blaim anybody, hate anybody, each its own way.

The theory btw is based on nothing but personal experiences. I care not if you dont believe me or tell me im either insane,not tell the truth or whatever. I know what is true and care noth for what others think..

The rabbit hole is very deep indeed, and if your not in very deep, then yes control is a breeze
