Reality, or Mundania, or the Land of the Dead, or whatever you care to call it, is a very large, very boring plane of existence.
Since the most influential beings on it are _homo sapiens normalitus,_ it is not the most fun of places. In fact, large areas of Reality are getting much worse as we speak, due to pollution by bad karma, industrial chemicals, and sheer hatred.
The physical laws of Reality are just as dull as most of its inhabitants. Standard Newtonian physics still works in most areas, though the much more interesting Einsteinian paradigm is coming into more and more popularity. Even the direction of Time is dull--only going forward, never stopping to look back or any of the things you expect to find in a civilized dimension.
Only the most thickheaded of thickheaded humans actually _like_ Reality: these are known variously as Realists, Jerks, or sometimes Assholes. You can usually tell a Realist because s/he has no imagination to speak of, and an empty stare in their eyes. Realists should be avoided at all costs, because having to face Reality has driven them barking mad.
Luckily, alternatives to Reality are becoming more and more frequent on the Earth, thanks to advances in religion, mysticism, heavy drugs, and the technological revolution. In fact, if you're reading this, chances are you're no longer connected to Reality as firmly as you once were.
