So i had a lucid dream last night and tried the method where a DC transforms you, so i went up to a random dc and said "Ok can you make me into a different person now?" They responded gleefully and happily tried by waving their hands in front of me but it didn't work. I told them to try again and it took several times for it to finally work. Once it finally did work I was a different person, but i found it hard to keep staying as that person, I had to keep saying things that i thought they would say and I kind of felt myself transforming back into myself. I suppose it gets better with practice however like everything in lding. Cheers, and thanks for the help!
