Andrei has had a few of these too - really scary, like a superduper tantrum, but all while he is asleep. I found I had to try and wake him up, as soon as he woke up he settled down. Either that or just use all your muscle to hold him close to you till it passes, or else he could hurt himself. A doctor in Malaysia told me to give him some medicine whenever it happened, but I didn't want to do that.
I notice it happens more when he is ill or teething -- could that be the case for you?
