im 20 weeks pregnant and for the past week or so ive been having really vivid scary dreams. usually i have normal dreams and dont even remember most of it by the time i wake up. ive been waking up suddenly 2-3 times a night afraid and remember every detail of my dreams.. its worrying me? does anybody else have a similar experience or am i just going nuts? hubby thinks this is normal & im overreacting but its some freaky shit...
