Witchcraft Lyrics

Cover art for Witchcraft lyrics by Pendulum

I think it could be about a close friend or relative of this girl who has died, and she tries to drown her sorrows in alcohol and drugs (the club reference). But her drink was spiked one time, and she gets home then passes out on the couch. The friend's spirit sees all this going on, and tries to save her from the bastard who has followed her home to rape her even though the friend is really helpless because he's only a spirit and can't do anything.
