Sara is about a child Stevie Nicks conceived with Don Henley. She said she would have named her Sara if she had not aborted the child, and it was a girl. If you look at the words, it's clear what the song is about. "Wait a minute, baby, stay with me awhile"
"All I ever wanted
Was to know that you were dreaming
(There's a heartbeat
And it never really died)"
