A dream of falling

In a dream
he climbed a tower
built from ancient seashells,
stained glass shards
and tide ravaged stones
with each tentative step
he reached further and further
into the golden uplands
of his own history
but the footing became loose,
treacherous and unsure,
his grip became tenuous
a slip became more
and falling backwards
he descended, screaming
toward his future.
