J-Rock,
Lucid dreams are as real as your normal waking life. There's no difference, other than the fact that it's just a dream. Still, the feeling you get in your stomach when making a huge drop on a roller coaster, or the pain you feel when hitting your knee, you'll both feel in your dreams.
Lucid dreaming is a skill that I picked up after reading the PhotoReading book, and it's still taking an ongoing effort to continuously improve. I had my first lucid dream a few days after reading the book and talking about it with others.
