I got into lucid dreaming a few months ago and I have them all the time when I take naps. I rub my hands togethor and everything to make it longer, sometimes I can manipulate the world sometimes I can't. The problem is nothing seems to last longer than 30 seconds to a minute for me and the majority of lucid dreamers. Yet there are many people who say they have 15-30 minute long lucid dreams.

What is the difference between me and other dreamers here?

I also seem to lack control, some of my first lucid dreams I was able to summon characters, change the scenery but my last few dreams I feel the dream has not cooperated with me. I also feel like many of the dream figures are hostile towards me or indeferent. I feel like the dream kind of kicks me out if I am not nice or something.

does interacting hostilly with the dream make it uncoopoerative? Is it possible for the dream to "kick you out" beacuse of your actions?

or is this all just a matter of experience.
