Yes I have had at least 3 where I have gone to the toilet and have found blood :( But Thankfully I haven't bled at all. Mine come every night, and it feels like I don't sleep at all. Alot are about my partner having affairs :( I know he wouldn't but it plays on my mind alot.
I had vivid (and sometimes strange) dreams all through my pregnancies. So far this time, I've only had one...I dreamed I was spotting and went to the ER and they had a long wait and I started crying and a very nice nurse asked me what was wrong...then I woke up. Oddly, just a few days later, I actually did spot and learned I have a low lying placenta...
I think having vivid dreams is pretty common to pregnant women.
