To see or dream that you litter symbolises ideas and issues that you have discarded and have no more use for. The litter may also represent a situation or a person who may not be worth your time. Alternatively, the dream suggests that you need to prioritize and organize your ideas and aspects of your life. Your ideas may be lost in the clutter.
To see a litter of newborn animals in your dream is indicative of the amount of time that an idea has been developing or will take to develop. Look at the number in the litter to give you that approximate amount of time. Alternatively, the dream refers to issues of codependency.
