Solipsism, extreme subjective idealism, I often make this mistake
The world exists because of my existence, and the world disappears because of my demise.
I opened my eyes, and what I saw was not that they existed, but that I created them!
When I close my eyes, everything disappears because I close my eyes!
You are all illusions, and you are all created because of me.
Objective idealism, Laozi believes that "Tao" generates all things, and "Tao" is nothing
