To stumble may mean to fall into sin or to make an error.

Positive: Dreaming of someone stumbling may represent God causing your enemies to stumble and fall. If you stumble in a dream it could represent that God is there to help you get back up and to trust Him.

Negative: If you dream of yourself stumbling it could represent backsliding or deception. Stumbling could also symbolize to make continual mistakes or be overcome with sin.

(Psalm 27:2; John 11:10; Jeremiah 20:11; 1 Samuel 2:4).
