I have a method for dream control that has worked great for me.
There is a very well known way of getting a “Flying”-pill out of your pocket that makes you able to fly. Most people do get to fly from this.
Now my method is, to think in the dream that you have taken such a pill an hour ago already, so you can fly already, no need for the pill! And later on, when you’re used to flying, you don’t need to think about the pill at all anymore.
Works great for me And not only for flying, but for everything
