Whats going on with me?

[shift_tao]

I know when I am being attacked... telepathically, energetically, etc... but it never 'gets' to me.  I've been attacked many times but the attack seems to fade the closer it gets to me (i know that saying 'an attack is getting closer to u' isnt accurate but it is sufficient for this question).

I don't think someone's ever successfully attacked me.. and I don't know why.  I rarely consciously make shields... does this make sense?
