Mine were wayyy bad in first tri, i used to have the sort of horror nightmares, that if they were to be made in a film they would be banned! Terrified and really disturbed me!
But yeah now im in 3rd, I get them now and again. Ive had alot of sex dreams as well? Last nights was quite pleasent. I had a dream that I slept with Olly Murs and he had a big widge.
But yeah i think its pretty normal to be having odd and vivid dreams again later stages of pregnancy!
