In my dream

I had a dream last night about all randoms sorts. At 9 pm today I remembered a bit of it. I was with my brother and cousins and we were all chatting about something, and usually I am the quiet one, but I had a little story to share. Right after I started to tell it, both my brother and one cousin started talking about something else. Then I yelled at them and told them to listen to me for once in their lives.
If only I could do that in real life. I know I am a quiet person but when I have something to say people just ignore me, or someone/something will interrupt the conversation and the person I had initially started talking to will completely "forget" that I was saying something. I am sick of it. It felt so good in my dream, to see their shocked faces. I wonder if I will actually ever end up doing it in real life..?
