I've learned through experience that transforming your own body into something else can be quite difficult in a dream, and have only once had minor success in this. However, I had an idea. I have no trouble creating dream characters by saying "such and such a person will walk around the corner now" and lo and behold, the person with the characteristics I imagined walks casually from behind something (has a gun I can take, a dead person I wish to talk to, etc.). So, I figure, since it's quite simple to make things immaterial but still there, it shouldn't be too much of a stretch for one to simply summon a character, turn them around and "jump into" their body, possess them if you will. It might have strange side effects, like accidentally being backwards or struggling to control the body over the will of the DC, but I feel like this would be quite an easy way to transform the self image. Has anybody ever tried this, or tried other methods of transformation and met either success or difficulty?
