The best person,by far,to pass judgment here is a skilled,experienced Neurologist.Such a physician is best trained to determine if this was a "seizure" or any other neurological (that is,connected to the brain or central nervous system) event.
If it's determined that it's not neurological then one could consult a psychiatrist to see if it might be psychiatric/psychological in nature.
If you read the post to which I was responding, you will see why I phrased it in that manner.
