Ok so I'm having problem with my lucid dreams. I pretty often - atleast once a week realize in dream that I'm dreaming so I get lucid. Mostly I don't even do RC in the dream. I just get a feeling like "wait this is dream". So the problem is this: my lucids don't last more than like 5 seconds. For example last night I saw very realistic dream. I was in our kitchen. I looked outside and there were many cars on our lot. Then I saw many cars of same kind. I started thinking it's a dream. And I got lucid. I tried to perform RC, but I couldn't before the dream was only the middle 1/9th of my vision and the borders were black. Then the middle got real blurry and it faded fast into awakening. This is happening with all of my lucids. Any advice how to stop this and get good lucids?
