My grandma in law sister in law passed away this morning in her sleep. my grandma in law told me that she herself has been having some weird dreams. they think the sister in law was having a dream when she passed but she had altiztimers. can dreams and nightmares be related to death? or what about medication? my grandma in law has an pace maker and is on different kinds of medications at once if that has something to do with dreams. This has really scared me since my grandma in law has been having dreams. She keeps telling me dreams and death are connected.
