Agreed- it is an interesting thing to ponder on! I certainly feel that I have very minimal control over technology even when awake. Maybe the physical parts (hardware) to some extent, but the software and programs and coding? Bascially no control 
And Mercury retrograde making everything go haywire certainly didn’t help much with my technology self-confidence levels! 
It’s called lucid dreaming! It involves training yourself to realize that you are dreaming so that you can then bring some of your conscious mind into the dream world and take control. With some training and patience, I think it’s an ability that anyone can do and improve at- it’s a skill like any other! 
If it’s something you’re interested in, there are some more resources in the Lucid Dreaming Discussion.
Sweet dreams and good vibes to you too!
