Yes i can get what you call an aura, which feels like everythings closing in on me in and out, sometimes i get no warning, i go into a daze people speaking to me i have no recollection they are there.
My eyes then go up to the side and off i go into the fit, i fall to the ground shake turn blue have saliva etc......
I usually come round after 2-3 mins but need to sleep after it!!
It sux i hate it!
