When I was in the EMU (epilepsy monitoring unit) couple years ago , the patient in the room next to mine was having something like this. The whole staff would have to run into his room and restrain him and try to verbally calm him down.

Definitely plan to speak to his doctor, I’ve done some research and have questions

You need to talk to his doctor about this. Those are definitely types of seizures..

I’ve actually googled it and it can be a thing, but I’ve seen my son have a couple while he’s asleep. He’s also had episodes where he’ll seem fine and relaxed and out of nowhere anger with cussing and then back to fine and relaxed

Hmmm…I’ve never heard of rage seizures. I wonder if I have it since I get irritated very easily.
