No it's great that you ask! Not just for yourself, but other new members or students may want to see them answered as well.

And yes to what CL said about energy. For some reason, brute force or fighting fire with fire in a lucid dream doesn't always defeat the beast. That's because, and I preach this all the time, emotions drive dreams. So the more positive thought and energy you can put out in a dream, the less likely negative characters or negative elements will be able to distract your dream from where you want it to go. Also simply ignoring negative things and walking them off proves helpful.

Example of a true story: I was having a lucid where I was walking down a hall, and a big bear showed up and bit my hand. Instead of fighting it and wasting dream time and energy with all that, I just thought to myself "ew, annoying bear," as if it were an annoying fly, and turned right into a bathroom and shut the door. Bear gone.
