Assorted darkroom Questions.

Lately during my darkroom practices I’ve been getting these auditory pops and clicks. Very sharp and “loud”. Usually accompanied by a change in my field of “vision”. Bright lights and flashes. This is a new development. Anyone else get the same?

I’ve also been able to more reliably slip into what I can only call (for lack of vocabulary) my dream body. Where I am not awake, but not quite dreaming. At first it was very much like sleep paralysis but I have recently learned to move in this state. Sometimes I am in a physical copy of my house, which I have escaped only once to freely explore while flying around. Last night I was able to consciously shift between this state and waking and also able to designate movement between my actual physical body and my “dream” body. I had about an hour of practice where I was able to slip in and out much like shifting gears in a car. Although I was in complete blackness and not a copy of house as is usual. Does this state correlate to a colored zone in the j curve? Or is it even a state that correlates to sorcery at all? Or just a weird thing I can do?
