Imagination is perhaps not understood in the right way. It is based on the external impressions of all possible kinds and emotional reactions to them, experienced by an individual, that can be recombined into something entirely different, regardless of the state of consciousness. And that applies to the past, present, and future lives. But there are so-called conscious dreams, that you cannot imagine as they come from beyond. For example, you cannot imagine the density of LOVE in Heavens, nor the density of hatred, present in our atmosphere, nor the density of Nothingness. That has to be experienced.
