I'm not an expert on brain chemistry, so I don't understand the full consquences of this. On the other hand brain chemistry is not the only thing that changes in sleep. Another change is that large parts of the brain are deactivated. One particular area is the dorsolateral prefrontal cortex (DLPFC), which performs certain functions related to self-awareness. There has been some speculation that you become lucid when these functions are somehow activated in dreams.

I would better ask one more question if you dont mind:

"For me this change occurs rapidly and without any effort on my part"
If you can. Could you please go into more detail?
This is again very subjective and hard to explain, but it's a bit like when you're lying in bed with your eyes closed, visualizing things randomly. And then at some point you find that it's not just visualization but real hallucinatory experience with your body disconnected from your real body, and you realize that you are fully immersed in the dream already.
