Dizziness often causes the unconscious to become conscious. In other words, things that occur in our bodies that do not require our attention, suddenly are brought to our attention. We never thought about how we felt when we moved before, but with the presence of dizziness, we think about it all the time. Reflexes that allowed us to move (without thought) are now being drowned out by our need for control.
Green light dizziness is benign dizziness that we must feel in order for it to go away. As long as an individual has been diagnosed and has been told "it's good to be dizzy" then it truly is good to be dizzy. There are psychological and physical reasons why it is "good to be dizzy." When we welcome "green light" dizziness into our lives, we decrease it's relevance in our lives. Our body gets the stimulation it needs to heal and our sense of movement can then return to the reflexive/unconscius level.
(There are rules that should be followed when it is good to be dizzy. Do not practice these concepts without the guidance of a medical professional who has experience working with green light dizziness.)
