Nosferatu

While it is quite straightforward at face value - a song about the famous vampire known as Nosferatu - it would be fun to also interpret this song in a different way:

Basically it could be about a bipolar person whose depressive side manifests regularly. The darkness as opposed to the light manic side. Even in the days of manic happiness, the person knows that the darkness is always looming there, ready to rise its head.

Where ever you'll go I'll be Where ever you'll be I'll find you

The dark side is always with him.

I appear as mist and I come as fog

It is hard to pinpoint when it will happen and how to define it, or control it.

I fall as rain and I rise like dawn

Rain comes randomly at no specified time, but it is 100 % certain it will happen, just like the dawn. While the depression might be gone for today, it will come again.

Call of your angels or I'll make them stay My fate is written and I'll make you fall from grace You must leave your breathing life Only to be reborn in mine

The person knows it will be with him forever, and can bring him down from happiness with a heavy hammer. Then he will live the life of the darkness.

I am the legend but your father too I grant you my kingdom son

This particular line, I would be inclined to take this literally. The bipolar disorder will be inherited by the person's son, and the cycle (legend) continues on.

You'll live a life where death means no harm

He might be indifferent when other, even close ones, pass away. It affects him in no way.
