Was it a bad dream or something more?

my 2 year old woke up with a blood curdling scream, when we went up to him he was awake but when we picked him up to calm him he was shaking really bad, also his skin temp feels really hot (have to thermometer to Take his actual body temp) it has took 40 Min's for him to stop shaking he is still very hot, and will not go back to sleep the only thing hat has kept him calm is to put him in our bed and just lie with him, he dose not seem to be wanting to go back to sleep at anytime soon, could this of just been a bad dream or perhaps something worse (my partner used to suffer with night terrors could it of been that?)
