This is my workbook for Sivason's Dream Yoga course.

I started with trying Lesson #1 version 1, level 1 and 2, being aware of as many sounds in my environment as I can.
First most obvious sound was the little refrigerator in my room. It's such a prominent sound that it kept stealing my attention from the more subtle sounds, which annoyed me, and only further distracted me from my awareness practice.
I noticed the refrigerator has a sort of layer of sounds. There's the continual hum, a rattle, and a sort of bubbling noise.

There were a few other, less obtrusive sounds, like the birds outside my window, and the fairly steady stream of cars driving down the road, and other people doing stuff in the house. I only sort of maintained focus on all of these for a short period of time.

I think I prefer to work on version 2 for the next few days. In my lucid dreams I sometimes focus on physical sensations like stomping my feet, or touching objects with my hands to help stabilize and to keep my awareness from fading.

I will post more later on my observations while working on Lesson 1, version 2.
