Yes, indeed it is. Search for "Nina's Stabilization & Clarity Tutorial" it really helped me.

Basically, the most effective technique seems to be using hand examinations and really studying your hands, then using verbal commands such as saying out loud "STABILIZE NOW" or "FOCUS NOW". Imagine yourself being anchored to the dream, solidly anchored.

Last night I went lucid after realizing I was controlling an object with my mind. I carefully watched my hands as they became more solid and stable. I forgot to do verbal commands and visualizing an anchor, though, so as I opened a window to go outside in my dream I had a thought pop in my head that I was going to lose stability. I tried to spin but it was too late, the dream was already fading too fast.
