This might be a weird one, but do any dead relatives or friends show up in yours at times? Both my parents and sister as well as a good friend do in mine.
I was elbowing Lou Rawls in the ribs once when I was in line for karaoke feeling nervous in a dream but he's not a relative and I didn't know him but he's probably dead. Anyway he said "you'll be all right kid" but in a deeper voice.
