When you think of an oasis the first thing that comes to mind is probably something similar to the definition of the word given by merriam-webster.
It conjures an image of a place that is safe from what is surrounding it where unpleasant things like the heat of the desert can’t reach you. In the book Ready Player One however it is an Ontologically Anthropocentric Sensory Immersive Simulation which is a virtual reality device used to connect the player to the other players and many worlds that they can explore. The characters use this as a real oasis where they can pretend that the atrocities of the outside world can’t reach them and they can escape into a fantasy setting or a version of the world before they ran out of fuel. This escapism is a major point throughout the book because the world they live in is full of poverty and they have become reliant on a second virtual world for their economy, education, and entertainment. Besides sleep, food, and bodily functions everything can be done inside the oasis and they never have to interact with many of the unpleasantries of their real world. With technology like the hamster ball rooms and haptic feedback suits and chairs the characters can become fully immersed and even be able to touch and feel objects in whatever world they want to make their own personal escape to. However, they can’t escape from the real world forever since their makeshift fuel solutions will only hold up for so long without anyone trying to fix them. Though the oasis can help them escape from the world, it can’t help them fix it and eventually they will have to step out from their safe haven to mend the world they actually live in.
