I've been dreaming of Death lately does that mean the end is near?

No, I don't think so, but I do think that something in your life is bothering you. That's causing the dreams, something important is eating at you and in order to make the nightmares stop, you should take care of what's going on in your waking world. Also, are you near a busy street with sirens and noise at night? Is there other noise, TVs, something going on while you're trying to sleep? Perhaps some white noise, like a fan, very soft music, ocean sounds will help you rest at night. I know that sirens can trigger bad dreams, so by trying to obscure the sound, the dreams may stop.
