Nightmares during pregnancy..

Am I the only person who keeps having nightmares during pregnancy? Ones like serial killers taking over the world and having to live like you're in The Walking Dead, realising your family are secretly apart of this serial killer problem and then having to kill them for self-defence, only to find out they were never going to attack you anyway. I saw myself stick an axe in my father's head, while all he did was sit on the sofa smiling at me.. let me do it.. So many different nightmares but I wake up every day early hours in the morning almost in tears 😭
