It sounds like good old post-ictal confusion to me. I can't speak for everyone...and there are others MUCH more adept at researching this subject, but after seizures disorientation can be more than just dizziness. It can manifest itself in loss of ability to speak, to think clearly, loss of motor skills, hallucinations, and many other things I've heard others speak about.
For myself, I have similar side effects to what you just described...and they last about that long (or less) if I'm lucky.
I will look for post-ictal related threads and post some links back here.
Peace.
