I read somewhere that people cannot actually read in the dreamstate, because the part of your brain that interprets written language is not active when you're asleep. So I asked to explore that while I slept.
Guess what! I can't read in my sleep.
I dreamed I was in my apartment, which had the address in big numbers inside the front door. I was sitting at my dinner table, reading the Journal. I looked up to see what my address was, and the numbers just melted into squiglies and swam around in a tight circle there on the wall, until I looked away, at which point they promptly regained their original positions. I looked down at the Journal, which had the heading in large, bold font, and an entire page of text underneath. When I looked at the heading, the letters melted to squiglies and swam. The rest of the page was stationary. When I looked down to read the page, the heading resumed its original position, and the news swam around on the page. Argh! How frustrating.
I also know that when I was young, and all I watched on TV was The Lone Ranger, I dreamed in black and white. I now always dream in color, and almost daily I remember my dreams with a veil of vagueness.
I have sleep paralysis, and it is extraordinarily scary because I also have sleep apnea. This means while I'm awake, but paralyzed, I cease to breathe. It gives me a very floaty sensation, that comes in waves, as if I'm phasing out of my body, until I gasp for breath, which usually breaks the paralysis.
I can explore my own brain while I sleep, consciously awake in my sleep state... haha! What an awesome gift. Beat that without drugs!
