Lucid Dreaming and the Causal Body

Here a seminar participant describes a recent state experience he had, in which he was suspended in the empty, limitless release of the causal body, and watched his own thoughts and intentions crystallize right before his eyes.  The tone of the experience was somewhat similar to lucid dreaming, during which we can actually witness ourselves manifesting our dreamscape in the moment, so he asks Ken whether there is any relationship between these sorts of experiences as they manifest in the causal body and in the subtle body.
