Well if the dream is very realistic it reduces the chances of getting lucid but it never makes it impossible, it still can happen that you for example just snap out of it and realize it's a dream for no particular reason. With RC's you are pretty much on the right track, because as real as dreams are, if you happen to remember to search for flaws you will most likely find some. It can take some time till you get your first lucid but motivation is very important, believe you can have a lucid dream and you can.

And even IF your dreams were to realistic to snap out of it there are still other ways to have lucid dreams and to petentially fix that problem from within one of those lucid dreams, like WILDing. So in one way or another you definitely can have some lucid dreams.
