The world is like a ride at an amusement park.  And when you choose to go on it, you think its real because thats how powerfull our minds are.  And the ride goes up and down and round and round.  It has thrills and chills, and its very brightly coloured , and its very loud and its fun, for a while.  Some people have been on the ride for a long time, and they begin to question - is this real, or is this just a ride?  And other people have remembered, and they come back to us.  They say, 'Hey! Dont worry, dont be afraid, ever, because, this is just a ride.'
