I get them now and then. And I used to think that my only symptoms were the scintillating bits on the edge or center of my vision, and a huge headache shortly after and somtimes nausea.
Then I stumbled on this website: http://www.migraine-aura.org
One of the stranger ones (other then like Forced reminiscence, or Temporary Synaesthesia) was phantom phone rings. Today while walking around I thought I heard my friend Autumn's cell phone ring, but then decided it didn't when she didn't answer it. I recalled what I had read, and then sorta dismissed it.
Then bam! a an hour or so ago I started having the visual symptoms.
