The problem with super high quality dreams is that they're so real that you have a hard time believing in your powers. I've had several "more real than real life" quality LD's and I don't believe I've been able to do much in any of them in terms of control. Not all lucids should be controllable in my opinion, seriously, isn't it just too awesome to be true that you're actually in a world your brain has created that is so realistic? That in itself is enough for me. In time you'll be able to do a fair amount of control in those dreams too, but don't worry for now!

Dream control comes in time and with practice, it's mostly based on what you expect will happen and is not always that easy. You might expect a hot girl to be in a public bathroom, only to find out there isn't one because you've entered the men's bathroom. Believe in yourself! Use all the tricks there is and try different techniques, by that I mean mix passive and active control. You can also watch movies and gain inspiration from there and mimick how they use their super powers.

When summoning people I just call out for them and expect a faint "Yeah?" to be heard. After my second call I usually get a reply and voila, they appear from behind the corner

Good luck!
