Fortification Spectrum

A typical Fortification Spectrum is a zigzag figure like shown here:

Fortification Spectra

"The dots and lines inside the 'crack' were moving down and to the right in waves. I could not tell if it was in the right or left visual field. I did feel 'lightheaded', as if the air was low in oxygen about 10 minutes before I saw this. The aura lasted for about 15 minutes, and gradually faded away in 5 minutes. I did not have a headache after. I had been 'seeing things' like small movements in the extreme lower right of my visual field, for about a month around the time of this aura."
