Yes, lucid dreaming is great. It’s lots of fun, and can help you work out problems.
There is a downside, though. It makes you want to sleep more often, and people who dream lucidly may have other problems with their sleep when they’re not dreaming lucidly. (i.e. vivid, horrific nightmares.)
Lucid dreaming is a great topic. I used it as my topic for my graduation project when I was finishing high school, and the teachers reviewing my paper loved it. Not many people know much about lucid dreaming, but most people I talk to find it fascinating.
