About 90% of all my dreams are always about a apocalyptic scenario or end in one.
Sometimes they can be nightmares. This has been the case for a few years now.

Most of the time they are Post-Apocalypse and normally are about surviving, though I have dreams about the end of the world unfolding.
I also suffer from infrequent sleep paralysis which most of the time will make me hallucinate (visually and auditory) about what I have just dreamed about.

I have had a few really scary episodes, some of them sound stupid now but at the time they are petrifying. Things like zombies groaning and banging on my bedroom door, seeing a nuclear mushroom cloud out my window and the strangest, being bitten by a poisonous moth (yes i know moths can't bite)

I would like to know if anyone has any experiences similar to this or an explanation to why this might be happening.
