enraptured
enchanted

...all good words...

Kinda like a Pixies song

Where is my mind? What’s going on here?
It seems like only yesterday I was fine.
I woke up & realized that I was ok. That I was at peace.
Finally.
Where did you come from?
Out of the blue you’ve taken over.
My every thought is wrapped around your name.
What have you done to me?
Just all of a sudden… out of nowhere…
One day I knew nothing.
I was blissfully happy & ignorant
And now… now I just can’t seem to turn away from you.
Now I close my eyes & you’re what I see.
I open my mouth & your name comes out.
What is this?
How did I get here?
Where is my mind?
