[TOMT][MOVIE] a scene where there is a thread of life?

I watched many movies when I was young and there is one scene from a movie which has been pestering me and I want to rewatch it. First off I'm 99% sure the movie was animated. So all I remember is that there was a thread which represented the life you have lived, it was sort of woven with some parts growing brightly than the others and some parts were dark, I suppose I interpreted it as the deeds you have done? [Istg if this turns out to be from inside out or if it was a dream (tho i doubt a seven year old could have such a dream)] Sadly this is all I remember, if anyone can help me that would be amazing Thank you in advance!!

Edit: it may also be from a TV show
