I'm not afraid to reflect on an issue but I am afraid to dwell on one especially if it's negative. The energy produced from negativity takes its toll on me quickly. It will be let out in one form or another. Controlling that energy is important to me and I would rather avoid it. The dark thoughts I am sure are different for most of us and every ENFJ is a bit different. Mine used to go as far as being suicidal....its idealism turned all wrong. It can be strangely seductive. I am not sure what else to say or if I answered your question.
