I'm not sure I can go so far as to say that LD has resulted in a massive change in lifestyle or worldview, but my first LD did affect me in a positive, and fairly profound way. It showed me that I too could have these kinds of experiences; it showed me that dreams can be important, useful and worthwhile; it showed me that my consciousness is bigger, better and more rich than I previously thought. It improved my self-esteem, and increased my sense of wonder at the human mind.
