It's called All About Dreams by Gayle Delaney. The book is actually mostly on interpreting dreams, but there is a section on inducement. It's actually quite simple. I can write a quick summary and maybe save you the trouble of reading it.
1. Choose a night where your mind is clear and you're not overly tired
2. Write about what you did that day somewhere to clear your mind of all of the events
3. Think about what you want your dream to be about, why, how you are feeling while thinking about this, is this for a good reason, are you scared of what you might find, and other questions you can come up with. Write all that down.
4. Write a quick one line question (you can use dreams to solve problems) or request that sums up the dream you want to have. Make it simple but effective. Try different phrases before picking one that works the best in your mind.
5. Repeat the phrase you picked over and over until you fall asleep.
6. Sleep. That's pretty easy.
7. Record your dream and interpret it. This is probably the hardest part because dreams can be really metaphorical and almost impossible discern the true meaning. And that's why the rest of the book is about how to interpret dreams.
Good luck, I hope you are successful.
By the way if you do want to get the book, I must warn you, it is very dry.
