Oh boy so I ever. Just recently it took me about a week to locate information about the song (title, where I learned or heard it and so on) that went with the one sentence going over and over in my head "who's behind that false face, no body knows but me"

I got my answer about where I heard the song finally through talking to someone that I used to go to school with that told me that song came from 1968 and is a school learned Holloweeen song that hasn't been taught in my school since that music instructor left the school.

I use situations like this to learn more about myself for example in order for this song to be repeating in my head at some point after I learned that song I must have been mentally singing it during an abuse situation of some kind.

So now I have a good idea of the age of that memory piece that is the audio memory of this song. Next is to locate the sights, smells, tastes, touch and emotional sensations that go along with that piece of memory and I will have the "whole picture" so to speak of whatever the situation that caused that whole memory to separate into different pieces according to the five senses and emotions.

When I know all that, that memory of the song will no longer replay in my head unconsciously when I get triggered into remembering that song. Im guessing the fact that holloween is coming or looking at the holloween decorations in a store is the trigger because when I looked around while the song was replaying in my head I was in the seasonal isle of a store and people were talking about masks for holloween and this matches with the words in the song I was hearing.
