What is an illusion? I'm sort of confused. All my hopes or rather most of my hopes seem to be illusions, quite possible to achieve but unrealistic to occur. I make certain goals in life and hope some day I can achieve them or attain them. Life swerves in tango's- this side and that side leading me from one place to another. What's the difference between an illusion and hoping for something? Are they both the same, because sometime's I think that even though we hope for things and they don't happen it's just like an illusion although its realistic. Sorta confusing....
