What causes disorientation and dizziness when suffering from temporal lobe seizures?

I am 75 yr old woman diagnosed over a year ago w temporal lobe seizures. I am currently sorting out events from the last year that for one reason or another did not pass by the neurologist. Do you think the following is likely an example of anxiety, the result of side effects from meds, or seizure activity? The example is as follows: I was on a bus,for quite a long time deep in thought. I was thinking about a childhood event – pondering my mother’s behavior – really engrossed. I looked up and saw that the bus was coming to my stop, but when I looked out the window the scene was completely unfamiliar to me [even though it was half a block from my home.] I was disoriented, dizzy and very scared. The bus stopped. I stepped out. Everything was as familiar as ever. I was dazed for a little bit but by the time I got home I was fine. What do you think? Many thanks!
