Eat your breath

I would like to know what the following means or what it is supposed to mean, someone told me to find what it means and I will understand them. please help.

"Eat your breath, control your death, lay your pillow to rest."

Would I be wrong if I guessed that your friend is somewhat morbid? I've never heard the expression you quoted, so my interpretation is a shot in the dark. However, it sounds to me like a prescription for self-suffocation. And do you really have the first name "Altar of heaven"? SS
