Anyones kid have night terrors?

Do any of you wonderful mamas have a little one that has night terrors…my 9yr old has had them for yeaes and his doctor just keeps saying hell grow out of it and that its normal but i feel so helpless…my baby wakes up screaming bloody murder and crying and sometimes hell go running through the house other times i catch him before he makes it out of the room and im able to snap him out of it but he doesnt remember what scared him or how he got out of bed and hes so out of it. He also still wets the bed and when he has his night terrors i always tell him to go potty and i have to keep an eye on him or hell pee where ever hes standing because hes so out of it…i just dont know what to do or how to help him…
