Yes, I have that. What its this, Craig? Are we demon possesed? Im only joking 50% with that.
I see the flashes, and also I feel my heartbeat oddly getting more noticeable in specific body parts as the stomach.
Also, when I am lying down, everything its dark and I have my eyes closed, any sudden noise will make my body jump and I will see INSIDE my eyelids a sudden explosion of whiteness. One day it even looked like a white wall with words, like the page of a book. I also have a strange symptom at night sometimes, I am trying to relax to sleep and suddenly I feel like I am falling or tripping over, and as a reflex my legs do an uncomfortable spasm. Its like my body in those moments really thinks we are standing up in the ground and acts like he would do if we would trip over in that context.
This all makes me think in sympathetic dominance, nervous system disorders.
