Choking in your dream?

Last month i had 2 choking dreams in the one week. In the first one i drempt that i was choking up all this thick, black tar. In the second one i was naked and in this wooden hut. My ex boyfriend was taping on the window to see if i was ok. I sat there in the hut and choked up all this thick cream-coloured cotton cloth. What does choking/throwing up mean in your dreams?
