"Key person" in my dreams?

Ok so after the last LD I got I noticed ALMOST of my LD's involve my brother I mean in the moment I'm attaining lucidity he's there, I talk to him for a while then something makes "click" in me and I start wondering if im dreaming... then I RC and that's it... lucidity

The questions are:

Do you think he's a "Key Person" so I can get lucidity?
If yes how can I use that to get more LD's?

Be happy you have found a good dream sign and do a RC every time you see him in waking life :)

No, it is not him, it is what he represents to you in the abstract, that is definition. What is a brother to you?
