Examples:

 

"I mention you when I say my prayers. I wrap you around all of my thoughts. Boy you are my temporary high. I wish when I wake up you're there. So wrap your arms around me for real. And tell me you'll stay by my side."

 

This could mean she is in love with someone forbidden (a married man) and she enjoys the rush that comes from sneaking around to not get caught. She wishes he would stay when it’s time for him to leave.

 

"My guilty pleasure I ain't goin' nowhere. Baby, long as you're here. I'll be floating on air. Cause you're my sweet dream or a beautiful nightmare. Either way I don't wanna wake up from you"

 

She is hypnotized by his love and doesn’t want to realize the wrong she is doing.

 

Meaning:

 

It is symbolism because the person is the dream. That person can do and say nice things to her which is the “sweet dream”. The same person can ignore her for a while until he wants to use her again which is referring to the “beautiful nightmare”.
