I’m fortunate not to get the actual headaches, but I have other #migraine symptoms on a regular basis, including the visual distortions. For me it’s usually an open curve, with the line filled with zigzags flashing different colors, that starts at the center of my field of vision and moves to the periphery.
Last night I had one start *during a dream* and persist when I woke up. The weird part: the curve was rotated 90°: Open downward in the dream and leftward when awake.
Also I think it might have been grayscale in the dream (with full-color perception of the rest of the dream) and color when I woke up, but I’m not 100% certain
