Dream are eternal

My friend Nick posted an interesting observation about dreams:

Another reality filter.
We're all eternal beings, and our dreams are the experience of that eternity.
Eternity is living a life where everything is possible, as in a dream.
Being 'awake' is when a tiny subset of those possibilities are acted out in cooperation with other eternal beings - it takes effort.
Death returns us to eternal dreaming, to 'resting in peace'.
Pictures like this are so misleading, you don't dream 'in your head'.
Dreams are a full reality, they're eternity.
In our 'waking lives' little parcels of eternity still appear - our memories, colours etc., what some philosophers call 'eternal objects'.
