Try it and let us know how it goes.

Maybe try to incubate what your dream guide would look like. Take a few minutes out of the day to run through a scenario in your mind where you meet your dream guide. Imagine what you want them to look like. Keep running this visualization through your mind a couple times a day. Do it every time you do your reality check. Do your RC, then imagine becoming lucid, and seeing your beautiful non-witch-looking dream guide.

Then, when you fall asleep at night, run through it again. It may take a few days, but it should carry over into your dreams.
