When sleeping, we can’t be mindfulness – It is a little difficult. But when you go to sleep, at that time, if you go to sleep with positive thought, then your whole sleep becomes positive. If we go to sleep with negative thought, then our whole sleep becomes negative. Second, if daily, we keep mindfulness, then it can be experienced in dreams. We can have this happen in dreams – A habitual tendency thorough our daily activity can occur in dreams. If we’re not mindful in day, we can be carefulness in dream. So, two ways we can encourage mindfulness in dreams. Go to sleep with positive thought, and train day-by-day in positive thought and mindfulness.
