What should I do? Am I being stalked?

So, I was at Best Buy the other day because I was about to get my own MacBook Pro. When I asked for assistance this rather friendly looking man came over to me and starting helping find what I was looking for. Once he helped me pick it out, he ripped off the tag on his shirt and revealed a pentagram. I tried to run but he took me to some back room that was pitch black. He ripped off his clothes and tried to impregnate, me saying "You shall make a nice host for my demonic younglings" I managed to grab a sharp object next to me and stab him into the eye and escape. I ran out of BestBuy with my new MacBook Pro and my clothes torn. The people just stared at me like I was crazy. When I was home I started hearing things like demonic laughter and starting receiving nasty text messages from some guy named Lucifer. What do I do guys?
