Timothy Paradox

While at work (very much in real life), I was walking around back and forth (I'm a guard of sorts). I was dead tired, having slept very little the night before. While walking, I closed my eyes for a second. I saw people in front of me, including a man whose face changed the harder I focused on it. I tried to call out to them (mentally, I didn't speak in reality) but obviously the hallucination ended when I opened my eyes again.
