Everything is happening inside your head

I had a big realisation a little while back, one that is taking some digesting. I was watching a talk by Eckhart Tolle, who said that, in essence, my whole life is happening inside my head. As he put it, "We believe there is something going on outside, but maybe that's just our imagination!" Now, I had heard this idea before, but I never really grasped it as anything more than an intellectual concept. But this time it hit me right between the eyes; everything I call 'my life', every so called experience, every posession, even every person I only experience in my own head. This is mind-blowing, and I wanted to spend some time on it today, I hope you enjoy...
