A dream where you take a pill or tablet suggests that you need to choose carefully, put trust in someone or something, or improve your performance in some area of your waking life. Alternatively, the dream may imply that you need to be selective over what things or people you include in your life, you need to put more focus on your health, or there is some part of yourself or life that needs healing.
If someone else is receiving or taking a pill or tablets then it suggests that you feel that they (or someone in your life) is feeling unsatisfied or their needs are not being fulfilled in some way.
