Yep. Sounds like you were very very close to me. The short breaths thing...sounds like you were getting close to the transitional stage. I get really short, shallow breaths right before I phase into the dreamstate. Occasionally I accidentally "sigh inward" and take a deep breath. Usually you can't even help it, it just happens, but it does take you out of the experience normally, because you focus on it accidentally. You were close though, keep it up
