I often hear, mostly from the Lucidology videos on YouTube, that you aren't supposed to leave your body until after the vibrations subdue. Since I have never projected yet (I've only been able to enter sleep paralysis), it's been bothering me to wonder exactly happens after the vibrations then? Are you able to see your surroundings by this point or is everything still white? How can you tell you're ready and not just laying still like when you started?
