Crazy dreams

Everything I have read up to this point has touched on how your dreams can change & become more vivid during pregnancy. I had a couple of dreams about having a baby boy in the beginning, but otherwise nothing. That all changed in the last week or so. I am having dreams every night, VIVID dreams about this baby either dying or trying to come early! What the heck? I woke up covered in sweat the other morning & scared to death that something was the matter. Then Ethan started his dance party, and I felt much better. I know it's normal to have these dreams, but they feel so real. For all of you momma's out there, did you have these kind of vivid dreams too?
