A few years ago, I had my first night terror or hypnagogic hallucination. I'm not sure what these are...they always occur in my room (unlike in dreams where your house never looks exactly like it does in reality) when I am first falling asleep. Something/someone is always either attacking me or rushing towards me or just walking by my bed freaking me out. I usually "wake up" screaming. I now sleep with smoky quartz under my bed and other protective crystals and the occurrence has lessened. Around the same time, I started hearing this high-pitched squeal constantly. It never goes away, but it sometimes gets higher or lower in pitch. (I noticed it changed when I was getting Reiki the first time.) And recently, I have been waking up at 10:35 (I go to bed really early, LOL) almost exactly for days in a row with something that feels like a hallucination but is not as terrifying as they used to be. It's so vague and hard to remember right now...I can only remember a vague sense of movement next to me that is the same action every night. What in the world is going on?? Any ideas or similar experiences??
