Securing the Peg
Interpreters explain that whoever sees themselves securing a peg in a wall, ground, tree, pillar, or other object, it may indicate that they will seek shelter or refuge with a man associated with the object where the peg was secured. This points to seeking protection or associating with a specific figure.
