Sleep walking occurs when one's sleep is so deep or dream so lifelike that the body begins to react as though one is actually experiencing real life. This is the same concept as when someone talks in their sleep or, like in your question, laughs. Whether they are a baby or an elderly man, laughter in sleep is just the overflow of an incredibly joyful dream.
