Dreaming of a cloak means gaining protection and hiding from something. It is about finding refuge against the powers that may control or manipulate one’s life. If you need to make changes in your life then start by wearing different cloaks / clothes because it is time to change what doesn’t work for you and take charge.
Cloak in a dream signifies a time of concealment and protection. Depending on what you are doing while wearing the cloak, it can represent either fear or responsibility. If you were wearing the cloak inside a familiar setting and felt people were watching and judging you, then this could represent your feeling of being vulnerable to others.
