[Daydream delusion]

Limousine Eyelash
Oh, baby with your pretty face
Drop a tear in my wineglass
Look at those big eyes
See what you mean to me
Sweet cakes and milkshakes
I am a delusion angel
I am a fantasy parade
I want you to know what I think
Don’t want you to guess anymore
You have no idea where I came from
We have no idea where we’re going
Lodged in life
Like two branches in a river
Flowing downstream
Caught in the current
I’ll carry you, you’ll carry me
That’s how it could be
Don’t you know me?
Don’t you know me by now?
