Hi Sharon,
From now on try and keep track if your sz. happen when a low pressure is near. This will help your neuro out a lot. I did a little research and found what you are discribing re: seperation is a form of an aura sz. to get the details check out this website.
http://www.neuropat.dote.hu/neurology.htm click on epilepsy when the main page comes up and then go down to temporal lobe seizures and check out that site. It has the info. about the seperation you felt. Here's wishing you well and May God Bless You!
