Overwhelmed by Emotion

The past two nights I have woken up about 5 am from a terrible dream. Not the same dream both nights, but both high emotion dreams.
The first night I was saying goodbye to my very best friend who was moving away and in my dream, right before I woke up, I was on the floor in a fetal position sobbing. When I woke up, I felt like I had been really crying.
This past night in my dream we had been away from church for a couple of weeks and when we came back, heretics had taken over and had changed everything away from the traditions of the church. I was so angry about it, my husband actually had to restrain me from doing bodily harm to someone. When I woke up, again, I felt like I had actually been through those emotions.
Do dreams actually mean something? (My husband asked me what I had been eating!) The first day kind of made sense because we are actually having to say goodbye to a family we are very close to who are moving far away. And in the second one, we actually have missed quite a bit of church recently. But I am wondering if these dreams have more to do with the overwhelming amount of stress, especially emotional stress I have been under with the start of school.
It will all be over on Friday! I need the long weekend! I think I will try to get some peaceful sleep.
