I think you are onto something. It's not unheard of for past life memories to mix in with our other dreams. I would be confident in saying that there are some definite clues as to who you were in a past life. I would continue to explore this area...it seems very interesting. :)
I think it's amazing. Really...and, like Argonne, I would be interested in how the child interacts with you. Your familiarity with the boy would lead me to think that you've incarnated with this individual in the past.
I have several snippets I can share...
#1 - A door step covered in a thick layer of what looked like "dirty snow" but I knew it was ashes.
#2 - Standing next to a podium of some sort. It was really tall or I was really close because I could not see who was speaking.
#3 - A glimpse of a man...
I have an intense, almost nauseating reaction to German air raid sirens from the WWII period. To the point where its difficult for me to finish listening...
I wanted to post a video featuring the sound but I'm not sure how. :(
