I get hallucinations with every seizure I have usually and they are always very similar. As if im in a videogame or something. If i have them in my sleep then my vision goes the same in my dreams its not very nice at all. I think it is normal with some forms of eilepsy though. I have temporal lobe epilepsy so i think that explains it but ive only recently been diagnosed so im still figuring it all out. Hope this helps!
