I'm sorry for your loss. I'm sure he was coming by to say goodbye and I'm really okay. I had the same thing happen to me when my 20 year old brother was buried 35 years ago. I was the last of my siblings to arrive at the funeral home. As soon as I walked up to the casket, I swear I saw him sigh as if in relief that we were all accounted for. I've never encountered anything like this since.

I was quite shaken and walked over to the corner where my three of my brothers were standing. I felt people coming up close behind me offering comfort and sympathy but when I turned to see who was there, no one was within 20 feet of me.
