The environment in a dream signifies the self. The environment in a dream represents the physical and spiritual aspects of ourselves such as our attitudes, behavior patterns and attitude towards other people or situations.
Dreaming about an environment represents your life, your job, or your family. If you’re dreaming about a work environment that’s very stressful, it could be because you’re stressed out at work. The home environment is an important part of your life. It could mean that the people in your family are very close to you.
Also, a common interpretation is to symbolize an environment that you are in. This can be physical space (hotel room, office), work environment (a hotel lobby) or home environment (your own apartment).
