If the yoga is characteristic of your life in reality, such dreams are usually insignificant for interpretation – they simply reproduce ordinary events. However, if you do not practice yoga in life, this dream can testify to your desire to achieve bigger balance between reason and a body or harmonies from the Universe, or it can be a certain sort the reference to the confused situation in your life.
The word "yoga" comes from Sanskrit language and means union or merger. The practice is in itself a spiritual discipline and in dreams symbolizes that which is needed to achieve union with the Divine. The practice of many of the different forms of yoga actually opens many pathways to perception and can enhance our dreams, allowing us access to universal truths. To be dreaming of doing yoga suggests a need for a deeper understanding of our own impulses. Yoga can play an important role in maintaining a balance between work and healthy mind. Because yoga is a physical discipline, a philosophy of mind/body connection and a spiritual way of life, any or all of these significances can become apparent in dreams. A yogi (spiritual practitioner) in dreams is a representation of a wise person or teacher and alerts us to the need in us to find such a person.
