"Once I had a sweetheart", as sung by Cynthia Gooding, says:

One night in sweet slumber I dreamed I did see
My own dearest jewel sat smiling by me
But when I awakened I found it not so
My eyes like some fountain with tears overflow

"You are my sunshine" says:

The other night, dear, as I lay sleeping
I dreamed I held you in my arms
But when I woke, dear, I was mistaken
So I hanged my head and cried.

Same? Are there others? Thanks.
