Dreaming of being on the main floor of a building represents a foundation or a beginning. You may be setting a foundation for a project, relationship, or event in your life. Alternatively, you may be ready to begin a new phase in your life or start something new and different. Examine the condition of the main floor for more clues as to how you feel about this foundation/new beginning. If the main floor is decrepit or falling apart, it could indicate that you have not laid a proper foundation or do not yet feel ready to for the new beginning to take place. On the other hand if the main floor is in good condition, it could indicate that you have taken the proper steps to lay a foundation or are feeling ready to start a new beginning.
