I can go to sleep fine but i am anxious sleeping in the dark because normally when i wake up in the dark i get visuals like dim flashing or other weird small shape visuals i see. Not all the time but allot of the time. Also i wake up allot and when try go back to sleep where my head is between sleep/awake I get these little brain zaps and mild bangs that aren’t hugely loud. Brain zaps feels like when you drop a cable on the floor and these little bangs are like if someone is banging on the side. Eventually I head back of to sleep. I am guessing this is stress and anxiety related and maybe my sleep hasn’t been the best.
