A Thought Or A Dream

When I am asleep tonight,I'll dream of it
When I am awake I'll think of it
Still I dont know what it is
But it is a peaceful dream
Or a calm thought
It doesn't give me chills
Nor it reminds me of my darkest fears
Then itmust be a hapy thought
And tears of happiness it brought
When it entered in my mind
Or stepped at the threshold of my dreams
It wouldn't drive me crazy
It wouldn't make me mad
But bring a sad memory
Even in this happy hour
Then it will go away at day
But return in silent night
And haunt me as ever
As it had never before
