the Vacuum Cleaner Dream

I had the weirdest dream. I was in an apartment, and a woman there turned on a vacuum. I tried to turn it off, but I couldn't find the button. I unplugged it from the wall, but it didn't stop. Then I woke up. I was in a hotel room. I told a girl in the hotel who I seemed to know. She said there was no vacuum, but I could still hear it softly. Then I really woke up. I was in my room, where I had fallen asleep last night. I don't know who the girl in my dream was. Creepy, right? I had a dream within a dream! Does anyone know what a dream within a dream about vacuum cleaners means? Help!
