夜骑高加索 这首歌讲述的是什么

Ummm Ride on Through the night Ride on
Ummm Ride on Through the night Ride on
There are visions, there are memories
There are echoes of thundering hooves
There are fires, there is laughter
There’s the sound of a thousand doves

Ummm Ride on Through the night Ride on
Ummm Ride on Through the night Ride on
In the velvet of the darkness
By the silhouette of silent trees
They are watching, they are waiting
They are witnessing life’s mysteries

Ummm Ride on Through the night Ride on
Ummm Ride on Through the night Ride on
Cascading stars on the slumbering hills
They are dancing as far as the sea
Riding o’er the land, you can feel its gentle hand
Leading on to its destiny

Ummm Ride on Through the night Ride on
Ummm Ride on Through the night Ride on

Take me with you on this journey
Where the boundaries of time are now tossed
In cathedrals
