I can't lucid dream anymore, so here is how I get ideas these days. When I want to see a painting or hear a poem, I lay down with an iPad mounted above me. And then block out all light and sound by wearing Bose QC35 Noise Canceling Headphones and a sleeping mask. I first listen for each line of a quatrain. They come fast (the moment I pull my sleeping mask down). When the quatrain is completed, I then see the hypnogogic imagery of the painting that goes with that quatrain (sometimes the moment I pull my sleeping mask down, and often after trying several times again). If I don't see any image, I wait until I dream about it that night. Or add the quatrain to my website without a painting to go with it. I accept any ideas from myself that seem to have come from somewhere other than me.
