A tendril reaches out and wraps around whatever it finds, so it is read as attachment and the need for support. It can also stand for something slowly winding its way into your life.
Does the traditional reading fit your dream, or did it mean something else to you?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
