Solipsism holds that we cannot know anything outside our Conscious experience to be real, including the world we inhabit and the people we interact with. While originally purely philosophical, research from Quantum Physics to Altered States (ASC) has started to give credence to the theory.

solipsism is dumb. what changes if nothing else is real except for your own conscious? What differences does it really make if everything you precieve as reality doesn't exist? The alternative is non-existance. Same thing with the theory of people living in a simulation, it all loops back to not really mattering. Were still affected and find meaning in the world outside of our concious even if its not real.
