I was meditating yesterday not doing any energy work or anything. I started to see this whiteness rolling around in the darkness behind my eyes(very 3d looking). Its kinda like if you where to close your eyes, look up at a bright light and roll your head around. For a second I thought it was a real light but I knew that that was impossible because I had one of those night masks on and no light can get through that. Sometimes I see swirls of colors when I mediate but its mostly purple and just a spot. This was like a white fog swirling around. Was it just my imagination or was some type of astral sight starting to click on.
