It’s a bit like catching yourself breathing it’s something that you don’t consciously think about it's just something you do then suddenly you are thinking about it.
The breathing becomes difficult. Then you have to calm yourself down but it only gets harder to do.
You catch yourself thinking about someone you don’t want to think about, you shouldn't think about, and breathing becomes hard.
I catch myself thinking about you. I should be thinking of my lover. But as your voice fills my thoughts and I feel the ghost of your kiss the breathing becomes hard once again
