I wonder how it is that so many people, every person supposedly different, dream about falling. Surely it is something in the human physiology or composition of the brain that is deterministic enough to summon that feeling.
I've had dreams of falling a lot. In fact, I've grown pretty used to them. They're never the same scenario and they never feel good.
Another dream I have is of running. I don't recall if I'm being chased every time, but the thing I do remember is that I am running at like half speed. I try running faster and the best I can do is flying/gliding across the ground.
Which brings me to another point. The whole flying thing in a dream is so natural. It's like an action committed to muscle memory... like in real life you don't have to think about walking--you just do it. Flying in my dreams is kind of like that (not really flying, just about a foot in the air). That leads into my next point of text/symbols/etc. I've heard claims that you cannot actually comprehend letters/text in dreams because of some left/right brain separations. However, I'm extremely certain that I have. This makes me wonder whether it is not words I am reading but symbols that actually make me comprehend something in my head. For example, in real life if it is written somewhere:
"This apple is sweet"
I will know that the apple is sweet. Now that knowledge in my head is something I can comprehend in my dream, but I'm uncertain if that knowledge is passed through English/some scriptual language or just some random symbolic composition in my head.
I frequently have lucid dreams. They're actually pretty useful because when I'm in the middle of a bad dream, I can just cut straight out of it. But I do not have lucid dreams where I control everything (well, most times). When I try to control stuff, it usually ends up that I keep repeating something over and over again in a loop.
