I constantly dream about the apocalypse. Is this normal?

A friend of mine recently expressed concern when I told her that I dream about the apocalypse a couple of times a week. But it’s not always nuclear holocaust that fills my dreams.

Home invasion, armed robbery, airplane crashes, swarms of killer bees.

I spend many of my evenings struggling to stay alive.

It's not the best way to spend a night in bed, but it certainly makes sleepy time more exciting. I also like to think that my nightly experiences with these disasters prepare me for their eventuality, as this video does so well:
