Hi Chunger. First of all; My sincere condolences. Second, Wow. Profound is the word that I'm looking for as to describe everything between "dream" and "nightmare." "Dream" because it can branch into either subtle or nigtmarish. "Subtle" That's the word I like instead of your use of 'dead'.
I understand that the use of 'dead' echoes the nightmare to reflect, 'nightmares as dark and deadly" however, in this case, "dead" is too harsh to describe a baby whose never known life. "She is still___(She remains still) (subtle)...This gives the effect of the true Nightmare. Again Chunger, My heart goes out to you! My best regards and cheers.
