Can you improve your self-esteem and self-image in lucid dreams?

[Yuusha]

My self-esteem and self-image aren't the best, I don't exactly "dislike" myself or anything like that, but I know I should be able to feel much more content with myself. So now I'm wondering, do you think it is possible to use lucid dreams to "heal" yourself in these cases? For example, I have heard people like Robert Waggoner have lucid dreams where they asked to feel "unconditional love", and it seems reasonable that this should improve your self-esteem to some degree. It should also be possible to speak to dream characters and have them reveal something about you, and give you some advice on how to handle it all...? What do you think? Basically, my goal in the end is to get rid of any doubts and anxiety, so that I can freely converse with other people, flirt with love interests etc and feel proud of myself while doing it, without feeling uncomfortable all the time, and I was thinking that maybe lucid dreams can make it much easier to reach those goals?
