Louise Goffin was the first to release a version of this song on "Louise Goffin". On that version Stevie sings backup.
In this song, Stevie sings about someone leaving her. This man was strong and really helped her, and she's not sure she "can handle" making it on her own. She'd like to help him, too - to "make [him] smile...be there for" him. She hopes he doesn't forget her. She's been so worried that she can't do anything, she "can't sleep"...she needs someone to believe in her. For that reason, she doesn't want this person to leave, she needs his strength in her life.
For all of the above reasons, I think this song refers to Mick's brief affair with Stevie that helped her deal with not having Lindsey. Their fling fizzled due to concerns about Lindsey's reaction to it, and Mick left Stevie for Sara Recor - astonishing, isn't it?
I agree with Web-Mistress. Seeing and hearing the lines of this song makes me think of the affair she and Mick had. In 'Sara' Mick is 'the great Dark Wing'. Here she would like to 'lie and hold' him for 'one more night'. Could this be a double entendre? "Lie" and hold you? When they were together they had to lie, for both their sakes. When Stevie sings 'I dont think I can handle this at all' I think she is refering to having two failed relationships in Fleetwood Mac. Not only did she and Lindsey part on bad terms, but now Mick is leaving her too. This would make not only the dynamic of the band change, but would also alter the personal relations between them even more.
Going strictly on the movie Practical Magic & how the lyrics relate to the subject, I feel like the 2nd verse relates to the women of PM & how for so long they tried to make people understand who they were. "My mind wont rest & I don't sleep" - the community they lived in treated them like outcasts & I'd say the harshness of that treatment caused them to lose sleep wondering if the burning times would return. And that last line was a plea for understanding which at the end they got - "If you ever did believe, for my sake. If you ever did believe."
I don't think that this was necessarily about love between a woman and a man, but about the sister of her heart.
"You've left me now and it's seasoned my soul" This song is about someone she loves very deeply leaving..Her soul was seasoned- made better for having known this person. A very deep, intense friendship? "You were so strong, I fell to my knees... And I don't think I can handle this at all" Could she, years later, have been remembering her best friend's passing away? ( I don't know when the song was written). "One more night I'd like to lie and hold you" I do not feel was a line having anything to do with sexual union... Maybe she wishes she could reverse time.. "To make you smile I'd like to be there for you"... she wishes she could go back in time and be there for her, hold her when she passed. Not even in her dreams does her mind rest, she always thinks about her... Though the passing was long ago, I believe losing your very best friend is something you can never get over... Remembering... Asking her spirit to never leave her... In a dream, maybe, begging her not to pass on... On waking moments, wondering how much time she will have to spend until they are together again. "Have you forgotten me?"... Will her soul remember? "If you ever did believe" If you believe in the truest of love, you believe that someday you'll be together again... Maybe that is all you have to hold onto.
The movie was about the deep bond between sisters, how it will always be there for one another. I think this song was fitting because it is about deepest love.
