Hey Ellie - I'm sorry to hear about those dreams. They're something that I've had most of my life, but they get worse when I'm not feeling well or when I adjust meds. Its tough since they're so upsetting and jarring in the middle of the night. I actually haven't had one in a while, but there's times when I wouldn't be able to get any rest since I was forever waking up in a panic about something I was dreaming. Too, seems to me the med schedule might play a part - like taking sedating meds later in the day so they'll help to calm - I know that sounds totally obvious, but in the midst of the upset, I can never register to do the obvious.
I found that it would ease up if I was diligent about trying to rest well - minimzing the caffeine intake and trying to avoid eating a big meal later in the evening. When I can't sleep well I still swear by the warm bath and warm milk routine.
If it keeps up, probably wouldn't hurt calling your doctor, especially if you're still worried about doing something totally rash.
Take care Ellie, and I hope that you can rest peacefully tonight,
