Difinitely not night terrors. I don't mean to be so blunt but if you have been through night terrors with a child you know this is not it. My son went through them for almost a year. I received four black eyes and a bloody nose not to mention the complete feeling of helplessness. A night terror occurs when the child is fully asleep, they cannot hear you, feel you or know you are anywhere near them. All you can do is keep them from hurting themselves even if that at times puts you in danger. His doctor told me that even though it looks like it they are not dreaming when they have night terrors, if I remember it happens beyond REM sleep, definitely not during REM sleep so no dreaming.
You have something else going on here, I wish you luck figuring it out.
