I do.
When I was almost 10 years old, my died in his sleep on New Years Day. A few years later I was going to sleep, in the same house. I heard what sounded like a large person or people running down our hall in front of my bedroom door. I called for my Mom, as she happened to be opening the door at the same time. She told me to stop running in the house. She heard the running in the hall also. It was between us.
When I lived in the last house I was in,,, I was looking in the mirror, and someone put their hand on my shoulder. But no one was there.
My Mom died when I was 30. I was helping take care of her sister and was feeling very bad for myself when I had made the decision that she couldn't live alone anymore and I needed to find care for her. She was 88. I asked my Mom for guidance. I was sitting on the deck, no wind, no birds, nothing. I told my Mother that I couldn't handle this again, that I shouldn't have to and I needed her help. In fact I told her I wasn't going to do it, let someone else be the bad guy, ( of course there was no one else) Just then,,, a branch about 1/2 " across falls down on my head. It was her way of telling me to buck up and do it, they would have done if for me!
And the last is the best. My daughter was about 4 years old and would sing and talk and play in her room. Always happy. She would just be having conversations. I asked her who she was talking to ,,, she would say " my friend". No specifics. Not too long after that I was packing to move to our new house. I found one of the few pictures I have of my dad. I showed Hilary her Grandpa for the first time. She looked at it, and says,,,, Oh, its my friend! A couple years later she didn't remember that anymore. I am glad my husband was there, I would have fainted.
