dead dog

Date: 6/28/2016

So last night I had a dream a little dog got hit by a car. I heard it crying and heard the hit. Then this morning (not a dream but real life) I was driving to work with my husband and I saw that same dog dead on the side of the road. Then all day just felt odd, like there was a dark cloud hovering over both me and my husband. Weird stuff kept coming up at work all day then at home tonight. I'm pregnant, and my emotions are off the wall right now. Can anyone tell me what this could mean?
