There were weeks when I worked day and night, doing tasks upto 4 AM at night, and waking back up for work at 9 AM. After some days of this routine, I began noticing shadowy movements around me as I sat there watching the depressing white screen of my computer.

One time, I'd lied down for a while and as I opened my eyes to get up and continue, some shadowy figure stood up and hit my face with a hammer using all its might. It was barely visible but he went straight for my eyeball.

It was just a hallucination though, as I felt nothing at all and was too tired to be afraid at that point. But I've a feeling that if any person forces themselves to stay awake, the shadow people would start to make a dent in their reality.

I personally wouldn't dare to make an attempt like that. Wish you the best in your journey...
