I would recommend just reading this book
Amazon.com: Adventures Beyond the Body: How to Experience Out-of-Body Travel (9780062513717): William Buhlman: Books
You can even read the reviews of normal people who have experienced it. Even me after only 2 days of trying manage to become conscious while asleep, I didnt manage to wriggle out of my body but that was the next step, I didnt peruse it any further.
