Going to sleep i am fine as long as I have a side light on. Trying to sleep in darkness isn’t for me, my health anxiety makes me look for things because when your highly anxious and stressed like me recently it can cause various symptoms, like flashing lights and other stuff in the dark. The problem that bothers me at the moment is when i wake up middle of the night and try get back to sleep i keep getting these little brain zaps when I start to dream in between being awake and falling to sleep. So weird how i don’t get it when i go to sleep but when i wake up in the middle of the night and try head back off. Maybe my mind is really anxious and stressed at that point i dunno.
