A dream about a folder can be interpreted in two ways. One interpretation suggests that it means you are being careless and need to take better care of your responsibilities. Another possible interpretation is that the folder signifies your memories, feelings, or experiences which are neatly put away and organized by often ignored aspects of life.
For example, you’re trying to solve a problem but you don’t know where to start because everything is such a mess and disorganized.
Or you feel like you have forgotten a folder about something important and are now frantically searching for it in all the nooks and crannies of your apartment, after looking everywhere else.
Folder in a dream represents your subconscious feelings about something you have been ignoring or have not addressed. It is a warning that you need to take action on it or make a decision. The time to act is now.
