Often I feel we are in a dream world, even though we are told we definitely aren't, and our imaginations fuel other dream worlds, such as Second Life. Second Life is the millionth in a line of succeeding dream worlds, if you believe that imagination follows imagination. For instance, I imagine my character in Second Life imagining his own character (something like a Second Life within a Second Life), just as in real life, going the other direction, I can imagine myself being imagined.
If you think about it...
'Life is imaginary' is just as good of an explanation as 'life is real.'
