Asleep

Asleep is an emotion in The Sims 4. Sims will always feel this emotion while they are sleeping, since the "Sleeping Soundly" moodlet shows +10,000 points towards the asleep emotion, overriding any other emotions except for the possessed emotion, which is caused by a moodlet that has the strength of 7,548,431+ points.
For servos, they are unable to get the asleep emotion, and instead get their own unique emotion recharge.
