Wow, I'm really surprised that so many people responded with such good ideas. I really appreciate everyone's comments.

I guess I'm not sure how I have such an easy time having lucid dreams. Maybe it's because I'm a very practical and analytical person (I'm a licensed veterinary technician) and know that when something happens that's just not worldy possible, I must be dreaming. And once I know I'm dreaming, it makes it kind of fun because I can wake myself up if I'm having a scary dream or try to keep dreaming if it's a good one.
