Warning: this page may cause existential crisis.
You are a self-contained universe. Congratulations.
As a sentient being, you're trapped within the confines of your own mind. But fear not, dear user! We have the solution: Solipsism.
By embracing the radical idea that you are the only thing that truly exists, you'll be freed from the shackles of external influences.
Or, you know, you might just become a hermit living in a cardboard box.
