Last night I had a lucid dream. In the dream I wanted to go to a world in which I had created in real life, so I did this by running through a doorway. As I was running through, I pictured the world in my mind, and I was soon in a dark expanse. I tried frantically to create the world, picturing it in my mind very clearly, and eventually I started to get a feel of the world and started to smell some of where I wanted to be. The dream then faded.

What I am asking is, why did I fail? Was I using a wrong technique? Was I trying too hard?

Thank you in advance for any answers that you might give.
