Dream of keys

I dreamt that I was burying a chain with a cross pendant but I was having a problem burying it because the hole was too shallow. Then a cowork came alonewho is also a pastor and said "ddon't worry I will do it for you". I was scared in the dream because it was as if a dead gi was coming for her chain. I was hurrying. Then I ended up in the back yard of my previous home and dug a deep hole but it was not longer a cross but two keys and I threw the keys in the hole but some how I was thinking it wasn't placed there properly and if not the girl willcome and get it. I jumped in the hole to fix the key, the dead girl was coming and I was hurrying ti wrap the chain around the key.
