Well, basically even this hasn't helped me. For some reason, I decided that it would help me. But I found out while all of our dreams, including our nightmares, are a collection of images from our daily conscious lives they also have symbolic meanings. I was looking for a dream book but came across a blog about interpreting dreams, which is fairly more agile than the others. I haven't paused in my quest to understand why and what dream, so the professionals there is helping me hack my dreams way better than these sleep engineers will ever be able to, I think.
