Possible pregnancy dreams??

So my husband and I are currently ttc baby #1. I've had 1 miscarriage back in March and didn't really have symptoms when I was pregnant. We're currently on our 4th cycle and I have everything crossed that this month is our month. I'm currently only 8 dpo two days ago my boobs hurt but that's also a sign of my period so 🤷‍♀️ Anyway I've recently been having these crazy dreams at night like the ones that feel like a movie or the ones that feel totally and completely real! I've never had vivid dreams like that but it's been pretty consistent. A girlfriend of mine said that was one of her "early" signs that she was pregnant. Is that true? Trying to no get my hope's up but...we'll see how that goes.
