Well the issue is complex, I would definatley say that you can plant those types of ideas in your head. To the sceptics I would point out that dreams are your subconsious so dream control is basically the manipulation of your subconsious mind what matters is the degree of controll you can have. To be honest we probably convince our subconsious of things by our thought processes via waking life all the time i know i do. I think its dangerous and would take alot of practice. The safest root would be to do this slowly sometimes you change for a reason also if I may I think it would be alot safer to just talk to dcs and your subconscious so that you could understand yourself better. I personally believe that when you have a better understanding of yourself you have a better idea of what you have to do in your waking life to change yourself in some way. Everyone has a passion but you should also be open to other possibillities as well imo excuse the bad spelling im running short on time
