People as Dream Signs

Although this might have already been posted somewhere else, I'd like to state that a recent dream sign for me is a particular person: my mom. You're all like "I have no idea what you're talking about", but it'll make sense in a few seconds. Anyway, my mom passed away a few months back, and it's kind of funny that she's become my dream sign. For like a few weeks after she passed, I'd see her in my dreams, and I'm saying stuff like "I miss you" or "Hey, you just died recently". All the while, I'm WANTING my dream to be reality, which somehow caused me to realize I'm actually dreaming. But, it stopped happening after a few weeks, but it happened to me last night for some reason.

It's probably because I was "forgetting" about her somehow, and my mind tried to make me remember her. Does this seem normal to you? Has anyone else ever attained lucidity because of seeing someone that shouldn't be there? Any thoughts?

Daniel , I've only seen one person who has died in my dreams and it didn't trigger me either.

My dream signs should be my parents and younger sister who live in another state and whom I rarely see. I say "should be" as I should realize I'm dreaming when I see them but I never do. It's kind of hard to do RCs on people you rarely see. I suppose I could find of picture of them and every now and then look at the picture and RC.
