This song is about Hyde's post traumatic experiences with his past abuser. It doesn't always have to be sex, but a situation, or "dance" the abuser put the victim through in order for them to remember this conflict. Read closely, "I'm having sex with a ghost, 'cause she knows I'm alone. She's a freak in the sheets, play it cool." This implies his abuser sends him through an post-traumatic rollercoaster without even being there. She's a ghost. The song also makes multiple references of him looking to drug abuse in order to cope with this experience. Every time he gets close to getting rid of her image (by shooting at her with a metaphorical rifle), it will never disappear. In conclusion, this song is about the post traumatic flashbacks that a victim has received from an abuser.
