if you're still trying to figure out how to fake sleep: 1. Sleepers often pause between exhaling and inhaling and it's very rare for any sleeper to take long breaths, so instead of making your breathing pattern look like *exhale-2-3-4-5-inhale-2-3-4-5-repeat* like you're doing a breathing exercise, try for *exhale-2-3-pause-2-inhale-2-3-repeat*. 2. If you are pretending to be in deep sleep, let your eyes move a little while closed. Your eyes always move during REM. Also, small breathing sounds are made by everyone, not just snorers, so try to make some noise. Pressing your tongue backwards against your throat tends to help. 3. If you are pretending to be in light sleep, your eyes should be completely still in their sockets. If you know that you roll in your sleep, you'd probably do it in light sleep. You might also want to let your mouth hang open slightly, as people who are napping or in a light sleep tend to drool. People in light sleep don't tend to make breathing noises. 4. When you focus on your breathing, you'll most likely tend to breathe correctly; that is, in your upper chest. Sleepers don't tend to focus on breathing, funnily enough. Allow yourself to breath in a way which raises your stomach rather than your chest (sometimes this actually takes practice: you see it best with small breaths). 5. The final tip is for if you are being "awoken" from a fake sleep: Deep sleepers: allow around 5-10 seconds worth of waking techniques. Most deep sleepers are unfocused but not startled when they wake up, so try not to focus on anything with your eyes for at least 2 seconds. Light sleepers: 3 seconds maximum of waking techniques. Most light sleepers are focused and startled when they wake up, so a big breath through the nose, a few blinks and immediate focus are the most believable.
