Twice actually, The family dog died (under my bed) when I was a sophmore in high school. and I swear I woke up to her collar jingleing jangling in my room.
And two years ago I woke up the night my beagle girl passed. I believe she was attempting to jump up on the bed! Such a tough night. She had a step stool that she used to get up on the bed and I refused to get rid of it for about a month after her passing.
