Water

Water flows beneath the bridge, like memories slipping from the mind. Each ripple a distorted thought, wrinkled through the effects of time.
When the water reaches a fork, which path is followed cannot be changed. Will it lead to the narrowing trickle of dried up dreams? Or will the ever widening opportunities eventually lead to an endless ocean of wonder?
The water flows without care, seeking new pathways should one become blocked. Sometimes the water is gathered and stilled, sometimes it bursts free from confinement. No matter it's current position, the water always seeks for a way to continue moving.
Water will changed forms, from liquid, to solid, to gas. But at it's core, it is still water.  Though their form may change, some dreams, like water, maintain their core. Like water, they continue to flow despite each obstacle. And like water, they refresh and nourish those who partake in them.
Water is vital to life, and so too can be the simple act of having a dream.
