A veiled darkness descends over your eyes.  Sounds are oddly distorted, and
seem to come from a great distance away.  Your heart pounds heavily and your
fists clench
    unconsciously.  A rhytmic voice chants in your mind the words
'kill...destroy...kill...destroy...blood.'  Over and over it repeats until you
can think of nothing
    but wreaking havoc on all that stands before you.
You feel like yourself again.
