I've been doing something similar, only it's in dream time and waking time. I'll have a story-line going and then something from way back in my past, pops in. Something from childhood. For example, a piece of furniture or person or room from childhood....and this is dream time or waking.

I probably wouldn't have noticed it so much in waking time except it's been happening in dream time so much too. Edit: and when it happens in waking time, I go interact with the childhood symbol. It seems the thing to do. To me, my perspective is doing something...so I'm going to make sure I notice. Hope that makes sense.
