By the user of the site Reddit with the nickname "mangosarebomb". His grandfather died in 2017, and before that he went through the Second World War and strange things happened to him repeatedly.
“My grandfather was born in 1924 in Massachusetts into a large family and had many brothers and sisters, but most of them died in childhood under tragic circumstances. One died in a car accident, another drowned, the third contracted a rare and dangerous disease from somewhere, and so on.
When the war broke out, my grandfather entered the service in the navy and since then was very far from his family and could not see them often. He was once at sea hundreds of miles from the coast and from any other vessel. He stood on deck, admiring the dawn in the ocean, and suddenly he heard and unmistakably identified a very loud bell ringing.
This ringing was repeated twice and it was clear that this was not a ship's bell. My grandfather was smart and had a logical thinking, he understood that the sound of the bell comes from a completely incomprehensible place and at the same time it sounded as if they were beating a very large church bell.
This incident alarmed him, he could not stop thinking about it and could not sleep that night. And when, a few days later, his ship arrived at the port, a telegram from his house was waiting for him, where it was written that his sister had died. It happened a few days ago on the same day when he heard the bell ringing.
Fast forward to post-war times. My grandfather met my grandmother and they got married. Then my grandfather got a job as an engineer and often went on calls. And his company was very secretive in terms of information and demanded complete secrecy so that the "spies" would not know anything.
Once my grandfather and a colleague were summoned on a business trip to a certain construction site and he did not even know where they were going. My grandmother thought he was joking, but it was true. They were seated in a darkened van and driven somewhere that was very far away, judging by the length of the trip. And when they arrived, they settled in one room.

During the trip, the grandfather and colleague chatted about different things, and the colleague said that he is a “practicing Muslim” who has “guards” to protect him. My grandfather was also a religious person and reacted to this with understanding, but no more.
However, when they went to bed, something unusual happened. Grandfather woke up in the middle of the night and saw a crowd of tall people in black hoods around his bed. The faces were completely invisible and they just stood and looked at my grandfather.
And it was not sleep paralysis, as the grandfather could move. He spotted a "gap" among the people and rushed from the bed through it to the switch to turn on the light. But as soon as he did this, all the hooded people instantly disappeared.
The grandfather was very frightened and agitated, but with some feeling he felt that these people were the very “guards” that his Muslim colleague said about. They were probably called by him to protect him from evil in this strange and unfamiliar place.
And one more story from my grandfather. One day he was walking through his house, where I grew up, and suddenly felt a strong gust of wind that literally passed through him. At the same time, there were no drafts in the house. And soon he received a call that his brother had died."
