Crazy dreams

Ever since I have gotten pregnant I have been having these crazy dreams and ppl trying to killing me dragging me in the snow everywhere, or someone is a a killer and I have to try find who it is but than it really me and I try to cover it up,, to my husband wanting to leave for some nasty girls and other things they are just crazy and feel so real and I have a dream catcher but doesn't seem to be working.... Is anyone else having some out there dreams???!!!!
