About a week ago I had a dream where I was moving into my apartment. While I was unloading my belongings I realized that I had a lot of furniture in my room. It didn't all fit very well. While I was trying to rearrange it to better utilize the space I realized that I had all of these cafeteria tables in my room! Then all of a sudden massive amounts of people came in and started eating.
The clutter of furniture in your room could symbolize how your life is now cluttered with a lot of different experiences, people, lessons, etc. that are all trying to find time in your life. Just as you tried to rearrange the furniture to fit, you are currently trying to organize and balance these varied things going on. The cafeteria part may be showing that you are not satisfied with the food here or that you want to be more engaged in social interactions with others, like eating meals together.
