The black bell dream I believe is a symbol for rapture.  There was the black sky ~ as nighttime, as a thief during the night.
 
Black bells where made in different sizes, suited for farms, factories, taverns, schoolhouses, church, kid caller, family bell for dinner, and a fog bell.
 
There is a postcard ~ Strasburg Railroad Postcard ~ Road to Paradise in the sky  over the older style train with 3 passenger cars.  This is in the vintage area for bells.
 
So, All Aboard!
God Bless,
