Is it easier running before you walk when trying to visualise feelings from how the world once was.
The idea behind visualisation (guided imagery) is that you use the power of your imagination to help relieve symptoms or manage problems. Learning to direct and control images in your mind can help with relaxation and pain relief. Running memories appear stronger for me especially near finishing lines or the bell for the last lap, where as walking just came without any thought an automatic function no more memorable than how normal breathing was.
Visual images can take your mind out for some exercise when the body can not get out of bed though it can be quite tiring finding home through the fog.
