Sweet Dream/Beautiful Nightmare

I can be a sweet dream
Or a beautiful nightmare
Depending on how you treat me
Don't take me for granted
Or presume to know
Everything there is to know

I can be a sweet dream
Or a beautiful nightmare
Depending on how you act
Don't be a spoiled brat
But don't be afraid to say
How you really feel

I can be a sweet dream
Or a beautiful nightmare
Depending on what you want
I can be a sinner
Or a saint
I am someone you can't forget

I can be a sweet dream
Or a beautiful nightmare
Depending on what you need
I can be demanding
And aggressive at times
I am the oxygen you breathe

I can be a sweet dream
Or a beautiful nightmare
This you know is true
I am at times devilish
Other times I'm a guardian angel
Set to watch over you

I play on your mind
Day and night
Night and day
There's only one thing left to say
I can be a sweet dream
That you're willing to share
But if you do me wrong
I can be a beautiful nightmare
