Separation Anxiety

I am currently pregnant with my third child. I have both a boy and girl. It seems almost every night I have these horrible terrifying dreams of losing my children for eternity. I can't get to them and I wake up balling uncontrollably. I'm no sure why I keep having these dreams. When I was pregnant with my son I didn't have dreams like these. When I was pregnant with my daughter I had dreams about being separated from my son and couldn't get back to him. What do these dreams mean?
