The root of a tree in a dream indicates a man's origin and his religion. Its strength indicates the strength of his religion. Uprooting it indicates abandoning religion or moving from a country.

The root indicates secrets and hidden matters. Whoever sees tree roots exposed, secrets will be revealed to him.

The root is interpreted as a person's origin and lineage. Whoever sees himself uprooting a tree root is severing his family ties.
