Everyone's different, so there are no steadfast rules about POV when dealing with dreams or lucid dreams. Personally, my LDs are always 1st person, but I do have non-lucid dreams that are 3rd person. I've seen many people on here that dream more in the 3rd person. So I'm not sure if it's anything you can necessarily change (or want to try to change), but you just go with it and make it work for you.

oh and welcome to the forum!
