When I have those moledramatic, mushy daydreams this Simon and Garfunkel lyric general describes them:

I can hear the soft breathing
Of the girl that I love,
As she lies here beside me
Asleep with the night,
And her hair, in a fine mist
Floats on my pillow,
Reflecting the glow
Of the winter moonlight.

She is soft, she is warm,
But my heart remains heavy,
And I watch as her breasts
Gently rise, gently fall,
For I know with the first light of dawn
I’ll be leaving,
And tonight will be
All I have left to recall.
