I first heard about lucid dreaming about a year ago, and started trying to have one myself. Since than I have experienced a couple of them, but never really made any progress. Every time I succeed in realizing that I'm dreaming, I either wake up or am unable to control them. Only once I made a door appear, which let to an empty room where I summoned a butterfly but that was pretty much it. I also tried rubbing my hands together to stabilize the dream but I got distracted by what was happening in the dream and couldn't do anything. I also haven't been trying to have one very consistently but when I do, I usually succeed after a couple days.
So my question is, how do I actually control my dreams once I'm lucid? Hopefully someone can help me with this!
p.s. I hope my English isn't too bad, I'm pretty young and English isn't my first language.
