How to pretend to be asleep
Slow your breathing.
Why do you think people look so peaceful while they're sleeping? When you're asleep, your breathing slows down slightly.
You can practice a breathing exercise to relax and slow down your breath.

Available options:
* For instance, count backwards from 100 on your breath to get 1 count from 100. Then, try breathing out slowly from 100 to 150 on each inhale.;
* Lie on your back with your head turned slightly to the side so your jaw is about slightly tucked in, or just the left. Then, take a breath in and make a sound such as a " creaking " noise.;
* For some people, this exercise works best with short breaths. Others need to inhale a breath slowly.;
* Try breathing in through the nose for a count of four, and then out through the nose for a count of four. When you are sleeping, your heart rate also slows.;
