My wife's mother passed away in 2003 from cancer. After the funeral, family and friends gathered at her house for a final celebration of her life. The gathering went late into the evening. My son, 3 at the time, needed to go to bed at that point.
I walked with him up the stairs to where he would sleep. The room that my mother-in-law passed away in was upstairs, and straight down the hallway as you reached the top of the landing. My son and I walked upstairs together, with me holding his hand. As we nearly reached the top of the stairs, my son stopped and wouldn't move...at the point which he could just see down the hallway. He was staring straight down the hall. I looked at him, then down the hall to an open doorway to a completely dark bedroom. He just stared, and would not move any further. I asked him "Buddy, are you OK?" His response was..."Daddy. The light. The light scares me." I looked again down the hallway where he was staring into darkness. "Buddy, you see a light?" "Yes daddy. It scares me."
I promptly picked him up and went back downstairs. To this day, the hairs still stand on the back of my neck when I think of it.
