the nether is terrifying because it is hell and monsters live there who want to hurt you. however, it gets even more terrifying when you think about Intentional Game Design. a world where you'll die if you try to sleep. you could get stuck there, growing wearier and wearier, until your eyes start to blur with the waves of heat rising from the earth. when you cave in and lay your head to rest the ground will explode. the souls trapped in the dirt will scream with you. you will never be heard. this world will rip you apart for the crime of being human. you cannot win. you cannot rest now. there are always monsters nearby.
