Dream: an idea or image present in the sleeping mind;
an extravagant fancy;
to indulge in reverie or imagination.

Vision: the act of seeing or the ability to see;
a picture formed in the mind;
imaginative foresight;
a supernatural apparition.

The boundaries often shift, the context overlaps.

Awake or asleep, what you perceive determines your reality,
or feeds a persona that would otherwise remain undernourished.

Now you may choose.
