I think we all use our imaginations in waking life, AstralProjectee... part of being a lucid dreamer is imagining where we'll be when we wake up in our dreams.

Were you looking to be more specific? Perhaps you're talking about a visualization practice where we create the images we hope to encounter in our dreams? If so, I've done that as well, though, because I'm a lousy visualizer, not too often.

I hope you might be more specific, because imagination is a subject often ignored on these forums, and it would be great if a decent thread about it happpened!
