They can track your brain activity to show you are dreaming, and not leaving your body for energy experiences across the galaxy.Maybe your vision is black when you sleep, because your brain doesn’t have the programming to decode the nature of what you’re experiencing.
Maybe you don’t remember what you do when you sleep, because your brain coding via neuroplasticity hasn’t built the proper neural networks to visually recreate any experiences you have while asleep.
Why is it black in your mind when you sleep, do you think?
If you actually were leaving, they could show when you were gone by a lack of brain activity.
