People may laugh while sleeping due to the brain's activity during REM (rapid eye movement) sleep, when dreams occur. Laughter in sleep can be a response to a humorous dream or a reflection of positive emotions experienced during that dream state. Additionally, it might also occur as a result of neurological responses to certain stimuli or muscle relaxations that happen during deep sleep. Overall, it's a fascinating phenomenon that highlights the complexities of the sleeping brain.

It is because you reached the highest point of laughing. When a person spend most of his/her day laughing, smiling and kidding around, his/her sub-conscious and muscles adopted this activity and become voluntary even while sleeping.
