My little basenji boy, his mom is full bred basenji but his father is a border collie/lab mix. Anyways he has really bad nightmares. I have heard the blood boiling screams and the crying at night. We use to pet him to put him back into a good sleep but that doesn't work anymore so we have to shake him awake. Night terrors happen and the doggy can't move just like humans. Im a vet assistant so she probably just had a really bad nightmare. If it was a night terror it would happen all the time and she wouldn't have jumped out of bed.
