The end of the world as we know it is such a potent image that it is part and parcel of almost every religion’s belief system.
In dreams the apocalypse (literally ‘the lifting of the veil’) is often the revelation of hidden meaning.
It has much to do with our fears, with the survival of the fittest and a reshuffling of those aspects of life that are important to us.
In such dreams it will be your beliefs and your faith that is the saving grace. Usually there is a particular symbol associated with your own basic belief which separates you from others in the dream.
