Night terror nightmare

I've been suffering from night terrors since I was a teenager and they're still going strong! Literally hate having them as have no idea what's going on! Feel worse for my boyfriend who has to deal with an irrational screaming woman in the early hours...Not fun!
Nothing seems to trigger them
But am sick of it now! My poor cat even gets scared when I'm I'm the middle of a terror.... Any other sufferers out there?
