Update: Progress. I had a false awakening after this change, in which I took off my sleep mask and tried to shut off the HGG, but discovered the battery was getting weak. Then in real life my kids woke me up. I consider this to be progress because it was my first reaction to the lights where I didn’t wake up. Unfortunately, rather than realizing I was dreaming, I did what I usually do when the lights wake me up: I take off the mask and shut off the device.
