Toothbrush – The toothbrush is the most personal artifact of personal hygiene known to mankind. If someone borrows your brush or comb, it is likely a little appalling. However if they take and use your toothbrush, it must be thrown away. This is because of its close connection with the tongue. See Tongue. If you dream about brushing your teeth it means that you have said something that has left a bad taste in your mouth. If you dream about gagging while brushing your teeth it means that something incredibly foul has left the bowels of your heart that is really going to be difficult to take back.
