Lyric discussion by Me2 

the dreamgirl in his bed is the spirit. this is the denoted feminine half of mankind (she is called pro 8:12 "wisdom") that he ever seeks after receiving the word (the masculine half). salvation begins at the recognition of jesus sacrifice for man. we receive the "word". afterwhich we seek after the feminine half to complete us the spirit or "wisdom". we seek after the spirit..in this case dave calls her his "dreamgirl". and to reach after her we must comprimise. we must die to or change our mind concerning previous choices we have made in life to be replaced with her choices.

we die to our choices while trying to receive the spirit.
