re watched inception and was wondering does anyone believe that its possible to do what they did? but with your own mind and subconscious?

forget about all thew movie reality rules for a minute; no "but that's not what inception means" retort. I just want to know do you think its possible to plant an idea into your subconscious that alters your waking behavior/ personality or have you experienced anything like that so for example you plant a seed to lift weights a seed that evolves into an addiction potentially. do you think that would be possible? thoughts?
