Islamic Interpretation of Dreams (Ibn-i Sirin):

A thimble in a dream means money, a child, a wife, a young intelligent worker, a vehicle, travels, or a needed competitor for the better promotion of one’s business.

A thimble in a dream also means dire need, tight circumstances, difficulties, or perhaps it could represent one who is crafty and who deceives children. Placing a thimble in the wrong finger in a dream means committing adultery, neglecting one’s prayers, or the falling sick of the person such finger represents in the dream.
