I think it could be related to something in the past you could examine in therapy, but im not totally sure...ask janine...I had those at one time too, mostly of elementary school, and I have to go back a long way to examine things kind of on my own, but I think that maybe in these things you suddenly remember there could be a part of your personality to examine...hm maybe janine would know about it...but in psychoanalysis that's something they look into...free association...stuff that pops into your mind as being significant, etc. But i'm not the expert.
