I have seen a really strange and scary dream this night. Do you know why I got this dream?

I have seen a dream in which me and my parents went to my hometown Falakata for vacations and decided to stay in my grandpa's home. Suddenly we saw some people burying 2 dead bodies in the field next to my grandpa's home. We were scared to sleep at night in my grandpa's home because the dead bodies were buried too close to the house. I was scared that some paranormal things might happen and we ended up staying in some hotel there. Then I woke up and was like thank God it was just a dream. What's strange in the dream was that they made a manhole made of concrete next to my grandpa's home and kept those 2 dead bodies inside the manhole and buried it. Also another strange thing was that in my entire dream I never saw my grandpa at all. But honestly this dream showed a really scary side of my Falakata.
