Phantom Semen and PMS

Okay so I admit that the title of this post is rather strange but it's a strange time of the month for me. (Yes, that!)
One day earlier this week, I could have sworn that I smelled fresh semen. Obviously not a realistic option in my home anymore yet I smelled it nonetheless. Which begs the question: when in withdrawal, is it normal to imagine substances that you are addicted to which are not there? It was rather odd because I have not had any physical contact with semen in almost 3 months....hmmm, more mysteries to ponder, I guess!!!
