The number 412

Hello all

Hmmmm...this is interesting, it's been happening to me for about a year...

For no apparent reason I will just say "412" in my mind...well ok, I will say in for a number of occasions:

1) When I'm confused and don't really know what just happened to me.
2) When sometimes my mind wanders to frightening thoughts, I say "412" in my mind and it sort of "gets rid of" the frightening thought...
3) Sometimes for no apparent reason.
4) Sometimes when I'm thinking...
5) When I see something funny..

This number just pop's into my head when I'm not thinking about it and I just wonder if it means anything-as for how I feel when I say this number: I can be feeling anything from happiness to sadness, to sarcastic, to being in a humourous mood-so it's not related to any particular mood/feeling...

Can anyone please tell me how I can find out what it means?
