Nightmare/bad dreams

Stephy

21 weeks and for the past while I been having really bad dreams and some are nightmares most nights. The odd part is I dont have any complications in my life. I have 3 perfectly healthy little girls my 4th otw, my husband and I are really good, nothing is wrong with my family at all but 99% of my dreams are involved with them and really scary situations. Does anyone else have this going on?
