I noticed in my lucid dream last night that I was having a little trouble modifying my environment. For instance, I wanted to teleport myself to a different place, but I just couldn't do it. I don't know why I didn't just go outside and fly to the place, but in theory I should be able to just teleport, right? And when I was trying to make things materialize out of nothingness, sometimes it wouldn't work. Any tips on how to fine-tune my superpowers?
