My mom died in 1999. We were so close I would know it was her when the phone rang. Pre cell phones. Or I would think of her and she would call the same minute.
A few years ago I was driving home late at night from work, it was foggy and i was on a country road near my home, I heard her say "Watch out for the deer", I slowed way down after hearing that and a small deer appeared in the middle of the road. I just sat in my car crying while waiting for it to cross. She is still with me.
