Ok, I've begun in the past 6 months to a year having lucid dreams. Being aware I'm dreaming or that the environment around me isn't real.

I'm able to go where I want, fly if I wish, I can even walk into mirrors.

The problem is I can't control a thing about the environment itself. For example, I can't willfully manifest anyone into the dream - the best I can do is see them in a mirror but they're not there otherwise.

I've tried the 'open a door and they'll be there' method but no one ever shows up.

I've also noticed the environment changes without me doing anything. Like I left my bedroom, knowing it wasn't real, and it was a large hotel. I strolled around and saw a group of people, but they changed.

I basically can do what I like, go where I want etc, but I have zero control over the environment.

How do I control who comes in and out of my dream, what room is where, and how can I keep the environment stable?
