riot, war, disorder, disturb
乱 centers on a state of chaotic disruption: a riot, war, disorder, or disturbance where things are not in their proper order.
乱 is the modern simplified form of 亂. The older form combines a tangled thread component with 乚, suggesting threads in disorder. The modern form replaces the left side with 舌, which is a simplification and not the original semantic component.
The left side looks like a tongue 舌, and the right side is a hook 乚. Imagine a tongue lashing out in a hooked, twisted way, causing a riot of disorder and disturbance.
For ラン, picture a chaotic riot where everyone is running wildly: run -> ラン, and the scene is pure disorder.
