Feign/Detect Sleep (Proficiency)

Feign/Detect Sleep: People who pretend to be sleeping seldom do it right. However, most people don't know how to tell the fakers from those really asleep. Characters with this proficiency are trained to feign sleep accurately and to determine when others are feigning sleep.
This skill is of special use to ninja on guard duty and those infiltrating a secure site. A ninja will use this skill when listening to seemingly sleeping guards and guests. If he detects one who is breathing wrong, he can take steps to capture or silence the faker. Likewise, a ninja can use this skill to convince an intruder that he is truly asleep, so that he can creep up on the intruder from behind when his back is turned.
Acting proficiency can convey the ability to feign sleep, but the Acting check is made at a –4 penalty instead of the standard –1.
