Had a dream

My mom and I (I felt there was other family there but i only saw my mom) were at a military graduation and I realized I was dreaming right at the part where they were swearing in. As we were leaving everyone was crowding at the door and my mom made a big deal out of it. I told her “it’s not that big of a problem just get through the door.” It took all of 2 seconds for her to get out and she was still talking about it. I kept saying “all you had to do was keep going and everything would be fine.” She continued to talk to about it and at this point we were a good distance away from the arena. I shouted at her “All you had to do was keep going!!!!!” I can’t remember what she said but I could here in her voice that she was holding back tears. She had walked a little ways past me and I had stopped walking and was listening to her voice. She turned around and she had tears streaming down her face. I was shocked. In reality I’ve only seen my mom cry twice but this hit me different seeing it in my dream knowing that she was crying over me raising my voice at her. I get this rush of sadness and started apologizing profusely. I told her “Ok, I’m sorry, I’m sorry.” She started backing away from me while she was saying something and then she turned around and started running away. I felt so sad that I just woke up and layed there trying to figure out why I would have a dream like that. Out of all the dreams I’ve had this one has scarred me.
