In order to shift back to your current reality, it is important to have a predetermined safeword or gesture that you would perform or say in your DR. This would serve as a signal to your mind and body that you are ready to return to your CR. A safeword is beneficial because it instantly triggers the shift back to your CR. It is important to make sure that the safeword is unique and easy to remember and that you practice using it frequently when in your DR so that it becomes second nature. Additionally, you should also ensure that the safeword is not something that you would say in your everyday life, as this could lead to confusion or a lack of clarity when returning to your CR.
