Andrew never remembers his dreams either. However, he thinks in words. Seems to me you do to. I think in images. I don't narrate to myself very often in my head, I just see and feel things. I think its this that causes me to remember every blasted dream I have, from the beautiful to the most unwanted images. They've been helpful before but if I tried to decipher everything I ever dream I'd spend a lifetime working on it.

So yeah my theory is that if you think in words more you don't remember dreams as much cause dreams are usually image based so your mind is thinking it'd rather think of words. Meanwhile mine's going Oo pictures! nonstop.
