visible invisible

I swear I didn't see that thing moved on it's own nor did I see anyone in the room besides me. Don't get me wrong cause I bet it was just a hallucination upon blowing my nose hard. Yes, I am having flu. The weather is so bad these days. Anyway... I am vaguely sure that it is meant to fall now after 17263916 days being left untouched. Could there be rats? No. Could there be roaches? Euw. No. Well, one other explanation, I am seing things cause I had been logging in and out of the system for 9 classes for a total of 323 students in total. So, it must be the flu + the work that causes this hallucination and unexplainable encounters right? Rrrriiggghhht??
