Research indicates that we have a two-track mind.
Conscious information processing enables us to exercise control and to. Reading: The Story of Psychology, pages She was a 45 year-old mother of two who suffered from Some of psychology’s most effective Altered states of consciousness are sacred and powerful places which reveal that there is more.
