K.B.
My son also went through this although not every night. It is difficult to watch and to go through every night! Like the other posts said, they do grow out of it and they do not remember anything. Our son was very active and so it seemed like he could not settle down, so what helped us was a very calm routine before bed and sticking to it. If he did not nap, which was often, the night terrors would definitely occur at night, so down time during the day and before bed is what helped him and sticking to a regular bed time. I cannot remember what age it stopped at but he is 17 now and we joke about it with him! like others said, make sure they stay safe as they will thrash around, our son would walk straight into the walls and scream and look right through me-scary to see and then we just got used to it...
