That was a weird one!

Less than one hour ago I'm remotely working at my PC from home and all of a sudden the upper half of my vision becomes like I've looked at the sun too long then followed by waves of distinct blue dots. Maybe my imagination but it seems like my heart rate dropped some too. Not sure what that was. Normally my auras progress slowly from the center out to the whole vision field. Now I have a very low grade headache at the back of my head. Sensitivity to light is pretty high too. Not sure what that was but that was a new one for me.
