I've been playing around with lucid dreaming recently and had a fun one last night, along with one on Saturday. I've discovered that, while I can do almost anything, some things must involve activating the wrong part of the brain, because they'll either just not work or wake me up.

So far, I've discovered that, while text looks completely sharp and doesn't seem to change, it's impossible to read aloud. I tried, but I ended up stumbling over my words, because the meaning of the text was changing. I was able to recognize the difference between Spanish text and English text, but neither said anything; it was just a random jumble of words. I suspect that whatever part of the brain is responsible for comprehension of language just doesn't work too well. I did, however, meet an author in one of my dreams and I managed to follow him as he pointed out the parts of the book he wished he left out. I must have been listening to him more than I was trying to read the book.

I've also discovered that listening to music with the explicit intention of feeling emotional doesn't seem to work out. I have no problem with most things that appear to elict emotion (sex, etc.) but music just didn't work out. When I listen to music, I sometimes get this tingling down my spine. I went to listen to a song in a lucid dream, but as soon as I got that tingling, I found myself in my bed (with my limbs still paralyzed for a few seconds). Does this happen with happy (not spine-tingling) music too?

Any other things people have found it impossible to do?
