Discovered my Dream Sign (I think)

So this morning I did WBTB as well as tried to FILD (which as far as I can tell was unsuccessful). However, I woke up about 4 times and remembered 5 dreams total. Before learning about LD's a week ago I didn't recall a single dream, so having 5 in one morning is a huge deal for me.

My dream sign appears to be a person I used to be close with but no longer see or haven't seen in a long time. The person changes too. For instance, one dream had my ex-girl friend in it, but I haven't seen her in months. Another dream had a best friend that I had a falling out with, and I haven't seen him in over two years. Yet another person was a kid I knew in high school but I never once spent time hanging out with.

Furthermore, the condition seems to be that either:
a) A person is in my dream that I haven't seen in a long time

or

b) The people are all familiar but the location of my dream is completely obscure or unknown to me.

Any thoughts or ideas? Even when I recognize these people in my dreams I'm unable to make myself aware that I'm dreaming or to perform an RC until I've actually woken up. It's like I'm simply watching the dream happen and then I wake up, with no opportunity to gain control.

It seems that seeing a person you haven't seen in ages, (Kid from skool) In your dreams is a common dreamsign.
