They're back!

For almost two months we were night terror free.  Then. . .Bam! . .they are back.  Every night now, for the past two weeks, Paige has been waking up between 9:30 and 11:30pm (usually twice in that time frame) with night terrors.  I truly believe that they are terrors and not nightmares.  We have been very diligent with putting her to bed at the same time, with the same routine, nothing new.  She is always in bed with lights out by 8pm and falls asleep quickly.  Everytime we go in the room during one of the episodes, she is sobbing/screaming staring at the same spot, rigid, and won't talk.  One night I even found her standing in front of her shelves, batting at them with her hands screaming, "no, no, no".  It really is frightening for Mark and I.  We just go in, reassure her that she is safe, we are there, and pray with her.  We never leave until she responds to us, in a normal way, so we know she is awake and still not in the midst of the terror.  She always appears awake, but won't talk or respond to us until she actually is awake.  Please pray with us for her, that these will stop and she can have peaceful sleep.  Does anyone have any other suggestions for us?  We would welcome any advice.  Thanks!
