You may be asking yourself some questions right now...
Where am I?
You are on this page.
Who are you?
I am a bunch of words on a webpage.
What do I do now?
Maybe read this sentence or something.
What does this all mean?
What does anything truly mean? Right now you are reading text on a webpage which exists on your computer, which exists within the universe.
This universe is something we call "real", but is this really so? Everything anybody sees, hears, and feels is processed in the brain.
In fact, the brain creates it. Aren't we just living in a shared delusion that we all agree is "real"?
