A School and a bottle breaking

Hi, I usually don't dream but anything but when I do, the dreams tell me somthing. But this time I can't figure it out. Can you help? this was my dream...Well I was in a school as I was going downstairs thru a very long, short step stairs, for some reason I was afraid of falling. When I got downstairs everybody was black and dirty. (the people the walls, the floor)but when I got to the principals office everything was clean. It was as if the principal wanted to be there to show people that he cares for dirty people.but I didn't see him, I just saw the door open and the clarity of the room. but I didn't go inside. After that I just saw a brown bottle, as I was poring what was inside into a spoon the bottle was getting socked in like a toothpaste tube. Then I bit on it and the bottle cracked but none of the pieces fell off I just heard the noice and saw how the bottle was sucked in and cracked.

I don't know what this mean but all of it gave me a weird feeling. Help Please. thanks
