I don’t know about the others, but when I was a kid, I was obsessed with the “end of the world”. Everything seemed so boring and the way things were described in Revelation were so much more interesting than anything that stuff that was happening now. Rivers turning to blood, people floating up to the sky.. I mean.. that would stir things up. In a morbid way, I think dreaming about the end of the world can kind of be like dreaming of a zombie outbreak or an alien invasion. All the normal rules of society will be destroyed and things that matter now won’t then. Who cares if you get fired or missed a mortgage payment if the FREAKING END OF THE WORLD is here?
I think another thing is.. once the end of the world comes, you as a Christian will have the ultimate come-uppance. There’s no more debate about whether or not god exists and if he/she/it/.them does, who that god is. Once judgement day happens THERE IT IS. 100% PROOF! That you were right and getting what you deserve and all the wicked people were wrong and are getting what they deserve.
