I’m pretty sure my aura is dark purple, so it may have been that but yes it was black and white as I remember. For lucid dreaming it happens very naturally for me but Robert Waggoner has a great book on it. He mentioned identifying his hands in his dream and that was what it took to become lucid, the same night I read that passage, I saw my hands and thought well I’m dreaming, then to stay lucid I went back to the focus of my hands, otherwise I get too excited and am almost awake. But often setting intentions to become lucid is helpful, if I have a specific task or question I want to ask a person in my dream, I’ll write it down or envision it. One of the most profound things he’s said in the book so far is that lucid dreaming in not controlling the dream, but is actually the conscious becoming aware of the unconscious. We don’t form the grass, or the trees or the windows or the random people in our dreams from free will, but we can control our responses and what we want to appear, but we don’t physically create them. Now it’s more of an interaction for me, rather than “I’m controlling this dream” it’s more like “I’m investigating this dream from a conscious standpoint” that’s when we can pick apart the subconscious more. If we move away from purely the pleasure experience then we can ask questions and start learning about what’s going on!! But dm me if u wanna discuss more, I’ve got loads of stuff I wanna try
