Holding a thread in one’s hand in a dream means looking for an alibi or a proof to support one’s argument and win a case.
Twisting a thread, or tying it around someone neck, then dragging him or her in a dream represents a pimp soliciting clients for a prostitute. Knots in a thread mean sorcery or evil spells.
A white thread in a dream represents the dawn, and a black thread represents the night.
