Jack 'o' Lantern Dreams

How can I explain when you just don’t get it?
I’ll take half a grapefruit and tea
Why should I explain when you just won’t see it?
Nothing here but jack 'o' lantern dreams
Remember through the darkness that we waltz on a knife
For the union of disunion and fight
The contagious in their cages and the rest of us dodging the curse
When the answers to these cancers is far worse
Only if you can remember the ending
Can we then work back toward the start
Nothing here but Jack and his dreams
