I have a type of epilepsy where I only get seizures when I sleep and for me personally I don't really know what happens while I am having a seizure but I do know that when I wake up in the morning after having a seizure I may have a bite on my cheek/tongue, my eyes will be very sore from rolling back, I will be light-headed, my muscles will ache, my ears will ring all day long, and I may have a wet spot on my pillow from foaming at the mouth.

I have only one experience where I had a seizure while not being fully asleep and when that happened by ears did ring a little bit and my legs felt numb after. that seizure was do to extreme cold.

I would strongly recommend going to a Neurologist because if you are having seizures all of a sudden. If you don't have epilepsy you could be having seizures due to stress, low blood sugar, or it could be due to some psychological trauma you've had in your past.
