Seizures

I know baby seizures are weird, but baby's are also weird, has anyone else experience their baby freezing? He's stare off blankly into space at TV me mostly but in his bassinet just now it was like he couldn't move, he was looking up and to the right and I called his name and nicknames and his eyes looked at me but he didn't even flinch and his arm was limp and then he started to slowly move his legs so I picked up and he was fine
