If you live in a landed property, that is, a house with a garden, and you dream of one, this dream is a continuation of your reality. If you don’t live in a house with land, but you see dream imagery of one, it means you wish to reside in one.
If you had lived in a landed house before, this dream may be one of nostalgia, where your sentiments for your old home may have revived this memory to replay in a dream.
