It promotes good sleep, good dreams, dream recollection, increased intuition, increased spiritual and psychic awareness, and a bunch of other things. Really it was the practice that made me lucid dream more but the Amethyst has really brought it to another level.
I have a black tourmaline under my pillow too mainly because it helps to neutralize negative energies (helps with bad dreams) but also because, since it's black, it has grounding properties. This helps with the lucidity aspect. And I've definitely noticed that I have lucid dreams much more often in my own bed than anywhere else
You guys ever actually feel things in dreams? Something that's been happening a lot lately before I enter a lucid state is that in my dream, I fall off the bed. And I feel it. Rather than being shocked at that (because I think it's real... feeling yourself fall off the bed would lead you to believe that too) I just keep dreaming.
I'm not very good at lucid dreaming because my dreams are always intensely vivid but I can only control the direction they go, not the entire thing.
I can make things happen to an extent but when I try to hard to dream something up I wake up and I think it must be because I was TOO conscious of what I was trying to do to be... unconscious?
I keep a dream journal, but I usually only bother with things that seem significant or that I wasn't lucid for (because if I didn't influence it, there's probably some significance in there)
I think doing acid literally had an effect on my dreams. Not all of them, that'd be a shame, but now I'll often find that before I fall off my bed, my bed moves in a way that the floor moves when you're on acid. Except I can feel it moving, while when you're on acid, it's all visual. And I had a brief dream recently where I as moving like The Scream looks... all wavy and contorted, like you look when you look in the mirror... on acid. This wasn't a lucid dream. I was in a huge mall and I made my way up an escalator or something and then I couldn't stand upright and had to clutch onto the railing on the side of the walkway, and it was like I only half had control of my bod, while the other half just wasn't cooperating. Eventually I went into a room with some benches and then I wasn't me anymore and was really desperate for help. It wasn't scary but it was weird. I think it meant something along the lines of I've lost a ton of control and freedom in regards to my own life recently and can't do much about it until I grow a backbone and work to change that. Which is true
So basically it hasn't negatively impacted me per say but it's certainly had an effect.
