An Excerpt From A Chemist's Diary

I don't know what to make of these strange occurrences, and I fear that if I explain them to anyone else, I'll be branded a lunatic by society. So I write my observations this diary, both to keep my sanity and in hopes that if the unspeakable were to happen to me, someone in the future may be able to explain these events. Or, if not explain, then avoid entirely.

What I am about to write in these pages are true events, written to the best of my memory. At times, it may seem more like an outlandish horror story, but I swear, on my mother's grave, that these incidents are not fictitious. I realize that the bulk of the text may be overwhelming to some, so if you happen to come across this diary in the future, I offer one piece of advice to you.

If you ever find yourself alone, and you feel like you're being watched by something. Or, if you enter a room by yourself and are suddenly subject to inexplicable chills and feelings of panic, then it's there. Behind you. Hidden in plain sight. Staring you right in the back of the head. And if you ever find yourself in those situations, the only advice that I can offer is...

Do not look behind you.
