Thread: Do you think it is possible to use lucid dreams to fully change your personality for the better?

I have, for several years, felt fairly stiff and unable to relax preoperly among people that I haven't known for that long.
I always have thisvoice in my head telling me that they "might get tired of me at any moment", that I "might say something stupid that makes them think I am weird" and in general I am unable to feel relaxed and content among them.
This is especially annoying if I see some cute girl that I want to approach, because while I am not actually "intimidated" by girls the usual way (I can be flirty to them and relaxed among them in situations when it's as easy as possible to talk to them, like during playful team activities with the classmates at school or something), I feel too insecure about my overall conversational skills, and I feel like I will just get to that point when I cannot think of anything to say and end up silent, and then she might think I am stiff and hard to talk to and lose interest in me - I feel the same way in front of almost everyone I meet nowadays, and I have no idea why, because I used to be able to get friends very easily without thinking about it - it's probably something I have experienced in the past that has subconsciously affected me in some way.
And I recently started at this university program with a lot of new students, and right now we do a bunch of random things together every day in order to get to know each other - and sure, I have been at various activities and spent time with them, but I feel like there is something "missing": that abilitiy to actually relax and feel proud of myself without being uptight and serious-looking all the time (I do sometimes smile openly, but in general I tend to have an "okay, now what?" look on my face).

Anyway, do you think it is possible to use lucid dreams to practice these kinds of things to the point that they actually start becoming simple in waking life?
Of course, I will have to practice while awake as well, but maybe lucid dreams can help me get past that initial barrier and make it easier for me to practice "stiff" situations?
I would like to become more like my parents, they are very social and seem to be able to hold long unbroken conversations with anyone, while enjoying every second of it.
And I actually used to be like that myself, and I want to get back there, and lucid dreams seem like an excellent training ground.
