I'm in an expensive city hotel. In my room there are girls I went to high school with. Some of them are in the jacuzzi that is in the middle of the room. I feel insecure and judged.
While dreaming of a house suggests exploration of your inner psyche, dreaming of a hotel can represent occupation with your external more public self. It could mean you desire an escape from yourself or that you are in, or wish to be in, a more unsettled, temporary situation.
The condition of the hotel you dream about could shed some more light on the meaning of your dream. If your hotel is chic and expensive you could be desirous of these things in your life. Whereas, a hotel in an old, or dilapidated condition could represent unhappiness with your material possessions.
Hotels are public places and in your dreams will usually be populated with people in your life, ranging from family members to acquaintances, to strangers you may have seen. In my dream above, being in a hotel room with classmates from high school gives me an opportunity to sort out feelings of insecurity I might have in my daily life.
