My mom died 13 years ago. About four years ago my dad was on vacation in Arizona with his girlfriend. He said he was up watching tv and the hotel phone rang. He answered it and said it was my moms voice saying “I’m ok” he said he said “Cass?” And he said the phone was crackly and said tell HEATHER (me) I am ok” he said his girlfriend was confused why the phone ring. He immediately called me even though it was late and he was crying. My dad doesn’t believe in the supernatural but still to this day can’t explain that call.
