I had a very strange visual disturbance last night that made me worry I was dying and I got the worst sleep of my life. I was lying in my bed in complete darkness and when I closed my eyes, a bright white light slowly started to engulf my vision. Which should have been impossible as there was absolutely no light source in the room. It continued to happen every time I closed my eyes and I was sure it was the white light everyone talks about seeing before death. I have had what I can only describe as a PERMANENT migraine aura that appeared about 6 years ago and has remained in my vision ever since. It is a group of three weird little blobs that stay in the same spot and swirl around with little lines moving in the middle of them. I have an MRI scheduled in a few days to finally try and get to the bottom of what exactly it is but until then I have no idea and worry it might kill me. The last time this weird bright light with no source happened last night, my eyes focused directly on those weird aura-like blobs and I saw them really close up in detail as the bright white light covered my entire vision. It was terrifying and I was up all night waiting to die. I rolled over onto my right side and it stopped happening. It only happened if I laid on my left side. What is this?? Not the aura stuff, just the sense of bright light that isn't really there?? Is this normal??
