Interesting, MrAccident

I usually have a bright spot, or field, of light, which starts of as diffuse, then after a while it gets sharp edges. The spot is pulsating and the color mostly changes between blue, red and whiteish. Sometimes the spot is round, then it usually becomes smaller and until it disappears, after it disappears it comes back big again going smaller and smaller and so on. Sometimes it changes from a round spot to move of a field, so it has one sharp edge which is either vertical and horizontal, this edge generally move in a single direction for a while, for example it can move to the left until it disappears from the left side of my field of vision, only to appear again on the right side and then continue moving left. When I see the "spot" as a field with an edge, it's kinda like if I was watching the light of a lighthouse with my eyes closed.

Sometimes when the light is a round spot I can make it stop changing size so much and make it a bit more stable. I've been able to make the shape change somewhat like a square, but the edges are jaggy, it's not a perfect square.

Is that spot something similar to your spot, MrAccident?
