Really?
The first verse:
The other night, dear
As I lay sleeping
I dreamt I held you in my arms
But when I woke, dear
I was mistaken
So I hung my head and I cried
I always took it to mean the person is mourning the loss of a loved one and they dreamed they were still alive.
Also, I once heard that this song was about a horse named Sunshine. 🤷♂️
I read it as an allusion to the price of everything going up. But yes, eggs.
