It's not just knowing how you effect things. It's knowing that YOU ARE. Be aware of yourself. What you doing, where have you been and doing just before, noticing details.

Then sudenly in regular dream you will notice that YOU ARE. Where you are and how you got there. It's not just a method, it's more of a way of living. Changing your whole mindset. It will not happen overnight.

You know, how most of us go through our day like a zombie. Without noticing much, like on autopilot. If I asked you now, what color is neighbors doormat, or how many cars is in the parkinglot you just walked by, would you know? If we not noticing things during day, why are we thinking that it would be any different in our dreams?
