On Christmas Day 2020, some of my relatives told us that they saw my grandparents coming to our house after they had been dead for 5 years!

That night, while we were eating, they said they saw them sitting and eating with us. At first, we didn't believe them until I saw them with my father. We told the others and they were trying to understand why only we could see them. By 1am, when they had all left, no one else had seen them. The next day, I read on the internet that people who have died appeared on Christmas day, but no one knows why they appear on that day.
