Spiders attack

I don't know how it happened but I now have four spider bites in the center of my back. These bites are in circular formation, clustered together. They look very unattractive (despite the fact no one will see them) and they itch. So I will probably scratch at them, which will make the bites appear far more grotesque.

I imagine the spider did his/her work while I was sleeping. Of course, I don’t know of any spider webs in my room and so I don’t know how I will find the culprit. I think I received the bites on the same night after I had purchased this bedding from Ikea. Did the spider follow me home from Ikea? And, could the spider be Swedish?

In my old apartment I also had a brief encounter with spider bites but it was very short-lived. I hope this isn’t one of those things that follows me wherever I go.
