Is there a demon hiding behind my books?! I can’t figure out how it possibly ended up there.

Everytime I sit at my desk and start reading, I feel like something is watching me, but I can never see anything moving in the corner of my eye. I also feel the urge to reach out and touch a random book on a bookshelf. And I swear I know what I’m doing with my textbooks, but somehow something’s hiding behind them exactly where I would normally keep it.<br><br>What’s going on? Has anyone ever found themselves doing the same in your studies? Am I possessed by a learning demon?<br><br>Edit: I know what you’re thinking, “Mushrooms.” And believe me when I say, “I wish it were that simple.”
