Baby nightmares! Just me?

I got quite a strong feeling that I'm pregnant and a few symptoms but I'm not testing for another 5 days! BUT, since I've had the feeling that I'm pregnant, I've been having the strangest nightmares. For example, I'm holding my new born baby and then suddenly my arm morphs into a big metal knife and cuts the baby's head off! And another where I'm taking my baby out of their car seat and then drop them! Theyre so bizarre! But I'm just wondering if anyone else has these or had these?
