mysterious scar?

I don't understand this scar-like thing that's appeared on my neck.  It used to come and go away before but now it's here to stay, since the summer I think.  I wonder what it is, it literally looks like someone just took a knife to my throat and cut but missed.

I need help thinking of a cool story to tell people when they ask me about it.  Help me think of one.  You can see it (vaguely above my mole) here:

also i just realized that my "how frustrating" post was made the same date/the night before it all happened.  huh.  how curious that i couldn't meditate and felt a distinct wave coming before it actually did come the next night.
