Violent Shaking (seizure) Followed By Difficulty Breathing And Then

 
Violent shaking (seizure) followed by difficulty breathing and then falling into a deep sleep and waking up 20 minutes later confused and disorientated. This is the fourth time it has happened, yes it looks like a seizure when it is happening, there is no incontinence but there is some rolling of eyeballs and tongue frothing, don't think there's any tongue biting. Another one happened one week ago and the first one happened about 6 weeks/2 months ago and I think it could be happening whilst asleep also.
