That sounds like a really cool and amazing experience. Did you ever repeat that while lucid or try to push the experience even further (if that is at all possible)?

Just a quick thought: I assume that most people have problems meditating in their lucid dreams, because they will lose lucidity very easily when closing their eyes and stop getting visual feedback. At least that is the case with me, losing sight usually means ending the experience.

Anyhow, I would really like to know what your meditation practice look like, so keep it coming.
