A strange experience at my grandma's house in high school

When I was in 9th grade, my paternal grandfather passed away in my grandma's bed. After the funeral, whenever I slept in my grandfather's bed at my grandma's house, he would always appear in my dreams. In the dream, my grandpa would say, 'Hey, come with me,' but I always refused and woke up. One night, my mom slept next to me, but I still had the same dream. My cousin slept in that bed and was apparently fine. Later, I told my grandma and dad about it. My grandma got angry and said, 'This old man is trying to take his grandson,' while my dad said, 'Grandpa really liked his first grandson.' After that, my grandma's house was redeveloped, and we moved to a different house in the same neighborhood, so we threw away the bed. Since then, I haven't had those dreams after getting a new bed.
