What is the meaning in a dream of tombstone

My uncle was driving us to his house,instead of calling him uncle, I called him father,and I asked to visit his son on the last day we traditionally clean tombstones, he thought about it and said how about I sleep "front opposite" to his house and when I contemplated it for too long, he laughed

I walked in a cemetery with my dad but instead of going through the tombstones to go to where my late grandmother was, we did not go because it was foggy and there were some snow

Last night I dreamt thugs having destroyed my late father's tombstone and managed to moved him from the grave. He was able to speak and walk with some family members and I was afraid to come closer or even talk to him
