Darkness comes prequel

The speaker is trying to convince someone that there are signs of evil all around and that they are the only one who can save them. They ask why the person is laughing at them and question where they are being taken. They emphasize the urgency of the situation and express fear that it will be too late to act. You don't understand, why do you not believe me, when the signs of evil are all about you? Look at me, look at me! I'm the only one who can save you. The only one who knows how these creatures think. Who knows their weakness. Why do you laugh as if I were a madman? Wait, wait a second, wait, wait! Where are you taking me? Where are you taking me? Don't you see they are coming? Just answer me. Do you not see the signs? When the last of the day's light has disappeared from the horizon? You will see, yes, yes, you will see! And by then, it'll be too late. No, no, no!
