All of a sudden

How did this happen How did you become so important to me Nowadays why do I smile on meeting you Nowadays why are my habits a little different My eyes search for you everywhere for no reason Is this me or someone else like me I never understood the language of rain I didn't even know that I had a heart inside of me There's night somewhere and there's a day somewhere, But only loneliness was by my side Your eyes always tell me to stop, But I'd rather say, If it is a dream then please don't wake me up
