Another related question is whether subjects in an OBE can affect objects, or have the power of psychokinesis. On the whole the evidence is against that possibility. The last feature which Celia Green found to be common in OBEs is that a spontaneous OBE can have a profound effect on the person who experiences it. Sometimes OBEs can be very frightening, sometimes exciting and sometimes they provide a sense of adventure. Interestingly, Green found that fear was more common in later, not initial experiences.
Pleasant emotions are also common.
