Don't know the film, but I think the song you mean is as follows:
Artist: Dan Hartman Lyrics
Song: I Can Dream About You
Lyrics
No more timing each tear that falls from my eyes
I'm not hiding the remedy to cure this old heart of mine
CHORUS:
I can dream about you
If I can't hold you tonight
I can dream about you
You know how to hold me just right
REPEAT CHORUS
Moving sidewalks, I don't see under my feet
Climbing up from down here below where the streets see
me lonely for you.
CHORUS
I can dream about you
I'm gonna press my lips against you and hold you tight to me
I can dream about you
You know you got me spellbound what else can it be
Moving sidewalks, I don't see under my feet
Climbing up from the pain in my heart 'cause it's you that I need.
I don't understand it
I can't keep my mind off loving you
Ooo, now baby, I'm caught up in the magic I see in you
There's one thing to do
