You posted this as a answer for someone else's question. I believe this was its own question so I have moved it.

This is very, very common in DREAMS. Then you wake up and think it happened in real life.

It's not your grandmother, whether is this spiritual or not. If this has continued for several years, I would contact a Christian ministry to have the home prayed for. Most likely YOU will need to be prayed over since it seems to be a recurring thing. Still, this may not be paranormal, like JOY mentioned.
