It-itaw is native vernacular word for dream among the Igorot tribe.
Don't you know that only our soul knows to dream? Try to recollect (if you haven't forgotten) your dreams and check if they have anything to do with God. Is it not that all of our dreams, including our daydreamings, are of worldly and earthly in nature? That's because when our spirit dreams, it is not called a dream but spiritual vision, spiritual meditation, or recollection on God's blessings and love; things about how to praise and worship God in a manner which is approved unto Him.
