I struggle with this too. I can understand that my experience ("my world") depends on being conscious. I can understand that everything I experience is a transient appearance to "my" consciousness.
What I don't understand is how my world is basically the same as everybody's else world. How is it that what appears to my consciousness is basically the same as what appears to everyone else's consciousness?
If it's an illusion, then it must be a shared illusion. And if it's not an illusion, then how is this different from a materialist or scientific view of consciousness?
Shared with whom?
When you are dreaming, who is it you are sharing this illusion with? The other characters in your dream? Is the world of your dream your dream character's illusion, a shared illusion with your dream character and the other characters of your dream, or is the the illusion the person lying in bed sleeping?
