The Thread
Scholars have said that if someone sees themselves taking a thread in a dream, it may indicate that they are seeking evidence or proof in a matter concerning them. They referred to the Quranic verse: {until the white thread of dawn becomes distinct to you from the black thread} to support this interpretation.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
