If you actually read your cell phone instruction manual (who really does, though?), you may see a warning can also be found inside the phone’s manual that states covering the device with bedding or other material could restrict airflow and cause a fire.

Just ask this one guy in New York City over the weekend who did just that. The New York Police Department tweeted a picture of the damage and warns people the danger that sleeping with your cell phone such as that can have.

Don't put your cellphone under a pillow when sleeping or when charging your device.Please share this tip and b safe!

This isn't the first time (or last) something like this has happened. Last year, a teenager's cell phone did the exact same thing and she almost didn't wake up!
