Dream about underground room hints your need for contact and communication. You need to think about and possibly act upon. You need to express yourself to those around you. This dream is a hint for your need to be alone or that you are feeling alone. You are leaving behind old attitudes and are looking toward the future.
Underground room dream is an evidence for a newly developing relationship or idea in your life. Perhaps you feel limited or restricted. You are completely accepting someone for who they are. This dream is sometimes your attention to details. You need to learn to see the brighter side of things.
If you dreamt about underground room:
The current interplay of celestial energies will help you to realize that the person who is actually being most awkward within your current relationship is not your partner, but you. You have been so busy blaming them for everything that has gone wrong that you have forgotten to look at your own part in the problem. Until you do so, you will not really make any positive changes.
