Black and White

My most recent dream
was quite unusual.

I was arriving at a rather large
outdoor event.
It was obviously a celebration of some sort.

There were many people there.
Most were just standing around,
as if waiting for something to happen.

And then I noticed
that some of the people
were different.
After a few moments
I realized
that I was seeing some of the people
in black and white.
Most of the people were in color.
But,
for some reason
I was seeing some of the people
in black and white.

And then a large truck,
a flatbed,
started to proceed slowly down the road.
It was then I realized
that we were all gathered
for a wedding.

The flatbed was all decorated
as if in a parade.
There was a large woman on the parade float,
many feet high.
She was dressed in a bridal gown.
Except she was all in black.

And then all of the people,
both the people in color
and the people in black and white,
started to follow the float
down the road.

Why was the bride in black?
Why did I see some of the people
in black and white?
Why was at the celebration
if I didn't even know the bride?
