The thing about reality escapes is, there is no such thing. It’s not like you can run away from the universe, because even if you could, the universe would just expand definitionally to include your new location. When I play We Love Katamari for hours at a time, I’m not escaping from “the reality”, because there is no overarching objective reality to escape. I’m merely passing through a door from one reality to another.
Certain things tend to be given the name “reality escape” as a kind of pejorative label. Gambling, TV, video games, narcotics, fantasy novels, anime, pornography, academia, religion, Wall Street, theoretical physics– just about anything you can come up with, someone out there looks down on it as escapist drivel. It’s a distinction which is entirely subjective. To one man, Christianity is the sturdiest bedrock of truth; to another, it’s the opium of the masses. A lot of people take jobs, careers, and money quite seriously, but me, I view them as an elaborate game.
The generous universe does not constrain you to live within any one particular realness. Throughout your life, you’ll experience many planes of existence, sometimes more than one at once. If you play a game of chess, that’s a very low-level, discrete alternate universe with rigid, 2-dimensional laws of physics, but it’s no less valid a universe than wherever the players are visiting from. When you go to sleep and dream, your dream is a very high-level alternate universe, one where you’re an omnipotent deity (whether you realize it at the time, or not). There’s no way to rule out the possibility that the real world isn’t itself a dream, or even a “chess” game being playing by some extremely advanced intelligence we cannot fathom, like a marble pawn cannot fathom his human chessmaster.
Our purpose in the multiverse is to explore and enjoy as much territory as possible. We were never meant to spend all our lives tied down to one “serious” reality. That would be like living in a giant mansion all your life and never leaving the main foyer. The mansion is full of secret passages, dungeons, mazes, libraries, even magical portals to distant kingdoms. The foyer is just where you sign the guest-book!
Don’t try to run away from reality escapes– after all, that would just be a “reality escape escape”. Embrace them, be an explorer of worlds, color your life with variety. The more doors you pass through, the greater perspective you’ll gain overall, for although there is no master-reality, there are self-similarities between all the subjective ones.
I’ve created a list of one hundred (possible) reality escapes. As you look through the list, you’ll see things that you think are obviously escapist, and things you think are obviously Very Serious Business. But of course, that classification is subjective and arbitrary, and for everything on the list, someone thinks it’s a waste of time and someone else thinks it’s the meaning of life. So look through the list and question anything you think of as a waste of time
