I can whistle from my throat, I figured out how to do it from yawning and just kept practicing, the wife hates it because it hurts her ears but every time I yawn I have a habit of trying
I have a hypothesis that there is no such thing as lucid dreaming (before you get the wrong idea, I've done it before. My meaning is that it's misunderstood, not that people are lying about having done it).
That feeling that you're in control? You're just dreaming that you're in control. You're just dreaming that you have the experience of choice-movement-feedback.
How is the feeling of being in control any more real than other sensations you experience in a dream?
When you experience the sensation of enlightenment in a dream, do you say you were really enlightened, or were you just dreaming that you were enlightened?
When you experience the sensation of blue in a dream, do you say there was actually blue, or were you just dreaming there was blue?
Your brain telling you you're in control is just as suspect as your brain telling you there's blue. They are both creations of your brain for the purpose of the dream.
Whatever action you're taking in an attempt to demonstrate control is just as easily explained as something your brain created as dream decoration.
The question is, is there a practical difference between lucid dreaming and dreaming about being lucid? I like to think it's the memory afterwards that counts.
I can hammer nails and icepicks into my head. I'm very fire resistant and eat fire. I have a split tongue. I can keep my eyes open for a VERY long time.
TBF I'm a sideshow and fire performer so I'm cheating
Sometimes when I open my mouth really wide, I somehow spray a little stream of saliva, like from a squirt gun. It makes me feel like the dilophosaurus in Jurassic Park, but so far I haven't been able to do it on purpose.
If I press on the corners of my eye it forces air down my naso-lacrimal duct (that lets tears drain into our sinuses) and it makes a squeak loud enough for people sitting next to be to hear. I have a built in nose flute.
This is my time to shine, my body is full of useless, I can:
gleek intentionally (saving people a search: it’s causing the salivary glands under your tongue to shoot saliva, people often do it unintentionally when yawning)
open my jaw wide enough that it goes out of socket, and twofer I can then move it side to side and produce a loud popping noise
bend my thumb down to my wrist
cause my heart rate to spike for short periods even when at rest
I can also gleek but it's nowhere near what my grade 11 English teacher could do. I don't know how it came up in class, but, in front of the class, she turned sideways and made the biggest arc I'd ever seen: maybe 6 feet long
I remember when I was a kid we were all trying to gleek and some of us could do it easily. I never could, so anytime as an adult I accidentally do it, I can’t help but laugh.
I can fold my ears twice - so from the top of my ear I fold it towards the bottom of my ear and at the point where it folds I can fold it again across over the first fold.
I can bring my hands from the back of my body to the front (and the opposite) while holding them together. There might be a use for this if I ever get tied up.
