Dreams

When we dream,
the dreamworld seems to be very physical and real.
Most of the time we forget that it is only a dream and not reality.
A friend tells me she cries in her sleep sometimes,
because she dreamt of something sad,
though she couldn't remember the dream,
but the pain is so real that she still cried for a while after she's awakes...

No wonder Wes Craven can think of films such as 'A Nightmare on Elm Street'.

Would we be in fact living in the 'dreamworld' of a much higher conscious?
A world created by this superior conscious,
like how our conscious constructs a dreamworld for us when we dream?
