I've never seen people or animals but there have been many times I will see colors of the rainbow in a zig zag pattern flashing back
and forth from one eye to the other. My Epileptologist told me this was do to the optical lobe firing up and causing to much activity
in the brain. If this ever happens again tighten up all the muscles in your body and make your hands into tight fists for a few seconds
if you do it quick enough it will stop. I was told to do this back in the 1970's and it has really helped. I wish you the best of luck
and May God Bless You!
As Bernard mentioned often hallucinations relate to a person who has temporal lobe epilepsy. I have had this form of epilepsy
since I was a kid but before the seizures started I got wicked migraines then a yr. later the seizures began.
I wish you the best of luck and May God Bless You,
