Also I wanted to add, regarding your dreams, firstly it is great you have such vivid recall - its actually a gift. I have done lucid dreaming now for many years and your dreams can tell you so much about yourself. Dreams communicate through symbols and are rarely literal (a car in a dream is not a car - it represents your journey through life at the current time, for example). You are clearly aware you are dreaming, so when you start to spiral, play with this instead of fighting it. What we resist, persists (you cannot win that way), so go with the current and flow with it instead. You cannot die in a dream and not actually wake up - think of it like a play. Nothing can hurt you, no matter how scary.
It sounds a bit out there, but I have a neighbour who suffered from similar dreams and I loaned her a large piece of black tourmaline crystal and gave her some selenite. The black tourmaline helps with psychic attacks - she confirmed she had family doing that to her, the selenite helps you with clarity and peace - she told me the bad dreams have stopped. I am just relaying what has worked for another - up to you if you want to give it a try or not. In my own life, I have found some of the more "out there" things like crystals, to be very helpful. It's not provable or scientific, and I cannot show you why it works, just that it did for me and for friends I have helped. It certainly cannot do any harm and at the least, provides subtle comfort. By the way, if you try it, simply putting them near you (under a pillow corner or bedside table is fine). Hope it helps you sleep better.
