Epilepsy/Seizure Caused Hallucinations?

I have been reading about the different types of seizures and epilepsy and am pretty sure I have temporal lobe epilepsy (my neuro won't put a name on it yet). I just have a question. I spent a week in a neuro unit going from being just confused to almost a complete vegetable before my neuro finally ran an eeg and started me on Keppra. I have read that people hallucinate during seizures, but it also says the seizures only last 30 sec to 2 min. I was in the hospital a week, but it felt like years due to the constant hallucinating. I had a constant feeling of wanting to "make things right" or explain to someone what was wrong with me, even though I didn't know. Unfortunately, in my hallucinations, everytime I would come close to "making things right," one of my six children would die in some awful way. It was like a constant nightmare. Has anyone ever experienced anything like this? The hallucinations described here under different forms of seizures are exactly right, but they lasted way longer than 2 minutes... is that possible? I don't know what to think. I know that Keppra made them go away even though I was still confused for days later. I'm so afraid of this happening again. I'm mainly just wanting to know if anyone experienced seizures that caused long hallucinations like this. Thank you. :)
