Just before reading your piece, I read a chapter of Richard Bach's "One." The chapter discussed the origin of ideas. In this chapter, he and his wife are in a metaphysical place that is a foundry for ideas that are contained in crystals forged in the foundry. As they look into the crystals, they see lightbeams that I relate to your words that I highlighted above. Here's a passage from the chapter:

"They were at once eerie and familiar. Eerie that the matrix of lightbeams and iridescent planes changed from color at once into thoughts. Familiar because I was sure I had watched the same view behind closed eyes, struck by meteor ideas."
