Dream about old flat signifies something that you are holding onto for too long. The path to your goals are not going according to the way you planned it out. You may find yourself entangled in a situation that is not in your best interest, perhaps even illegal. It states destruction, hostility and the frustrations that you are experiencing. You are not owning up to your duties.
Old flat dream is an admonition for your childhood where the times were more carefree and simpler. You are under scrutiny. Not to max out your resources if you don’t need to. This denotes your desire to get off the beaten path. You are trying to control or manipulate an object.
If you dreamt about old flat:
As water needs a channel through which it can flow, you need a firm and sound base before you will allow your deep and intense feelings to surface in a relationship. You will realize that the person you are with is not someone who will give up at the slightest difficulty.
