This night I had a dream about swimming in a pool, after a wile i felt pain in my feet so I stopped for checking them and discovered that they were all violet and frozen. I started rubbing them to warm them up and in the meantime I realized I was underwater and I could breathe, I stopped for a moment to feel the sensation of breathing underwater, but then instead of wondering if that was a dream I went ahead accepting the fact that I could breathe, as if it were normal.

This is another little success, the next step is to notice the strange thing that is happening and asking the question "am I dreaming?"
I'm getting closer and closer to have my first lucid dream, I'm so excited
