I am terrible at lucid dreaming. Gave up after having only a few successful times. My experience though is, anything too far outside your normal real experiences will cause you to wake up.
I tried breathing underwater for a couple lucid dreams. I woke up before I would have inhaled water in the dream. I got scuba certified before my next attempt, and all the sudden, I was able to breathe underwater in my dreams.
Kind of disappointing. If I can’t break the rules of life in my dreams what’s the point of lucid dreaming? Maybe once VR gets good enough it can bridge the gap and give me close enough experiences that I can replicate them in dreams.
I think Goliath was a “giant” in the same sense that an NBA player is a giant. Not like a mythical species in the Bible, just a genetic anomaly family that was crazy big and strong. Meanwhile, the average height was back then was much shorter than it is now.
So think of a fairly average but smallish guy beating up Shaq and I think that’s what we are supposed to envision.
