Under no circumstances should any liquid or medication be forced down the throat of an unconscious person. Fainting for more than a few minutes requires medical attention.

Dreams that we remember are those that have penetrated through our ego defenses, their messages having begun to come into our conscious awareness. Often, we do not have a full understanding of the meaning of a particular dream. Awareness is a long and continual process. If you remember dreams in which you are fainting, the setting of the dream and the details leading to the fainting spell are important. Fainting in your dream suggests that you are unable to consciously confront the issue or the topic that is being raised by the unconscious. In daily life, we faint under specific conditions. For example, when we are physically ill or when environmental conditions, such as heat, powerful smells, traumatic events, or dramatic visual images, overcome us. In the dream, internal forces, images, or emotions that may be too powerful for us to process may have an overwhelming effect on the dream ego and fainting occurs. The fainting dream may be the first step in a process of becoming more aware of a particular area of your life. The unconscious will continue to send up messages and eventually you may be able to experience the unconscious psychic event that currently results in fainting.
