I have just had an almost identical experience to the person who witnessed the green mist. I had just laid down and closed my eyes when a very strong green light shone onto my eyes. It became deeper and moved closer. I was not asleep as I literally had just closed my eyes. I opened my eyes to see a light green mist sort of oblong shaped with a yellow tinge , there were in fact 2 or three darting around my bedroom for at least 10 seconds. The whole room was bathed in green light. My bedroom has black out blinds and no other light source was on in the room. The light was all around the room. It was like seeing the northern lights in my room albeit they were darting around rapidly moving across the room as if scanning something. Does anyone know what this was, am quite freaked out.
