It is not important whether the reality lies within or beyond your imagination.
The only thing important is the case. Here the case is: you think the reality lies only
within people's mind. No matter whether your idea is right or wrong, the is a case which
supports the absurdity of reality.
If you think the reality lies beyond your mind, it is also a case which supports absurdity.
That is why the reality is absurd: no matter where is lies, what you think about it, it is
always absurd. Your personal idea is only, and always, a case of absurdity.
