Yes . That happen`s a lot when it come`s to a Grandma Seizure . A pitma seizure is really spooky . You don`t black out . You see ,as well as hear what is going on around you ....

Yes it very possible. Many of us have an Aura or a prewarning sign , before the seizure. There are those amount of people , like myself and possibly you Mary , when we don't have that warning sign or Auras to let us know a spell is coming. So when we have the seizure , we may not even know that we had the seizure. Most of the a family member or friend would tell me that I had a spell. At times I would have bicker a little back , because I don't believe that I had a spell. But in the back of my mind I know they're right.

A number of types of seizures can cause a "loss of awareness". I have had thousands of seizure like that, I just had two yesterday morning and didn't remember a thing. A complex partial seizure will do that. It does that to me all the time many times I don't even remember having a seizure at all until someone tells me I had one.

You may know something is going on but not be able to speak

Yes, minor seizures whilst awake (not remembering) are petit mal seizures or absence seizures... These happened to me often when I was a teenager... Later they turned into tonic clonic seizures!
