This story occured to me 2 months ago, when my husband was out on a business trip. He really travels a lot. I should start by saying I've always experienced stuff like this, so now when it happens I just say "oh well..."
This house were we live now (we've been living here for 5 months) has a big open space where there's the kitchen, dinning room and living room all together. This big room has 2 doors, one is the front door and the second one is the door that goes to the hallway where you can find the bedroom doors.
One night I was watching TV and received a call from my husband. He was preparing to go to work (my nights were his mornings where he was). He asked me about our dog Whoopy, who is a cocker spaniel and I told him she was sleeping under the center table in the living room (I could only see her little leg). We kept on talking for another 10 minutes and then we said good night. It was 11:30pm already so I looked at Whoopy's little leg and said "come on girl! Off to bed!" and she just pulled her leg underneath the table so I couldn't see her anymore.
I was tired so I went to the hallway door and said "if you don't come in you'll have to sleep in there!", but I didn't hear her walking towards me. It's very easy to know when Whoopy is walking because she has long nails (the guy at the shop refuses to cut them shorter when I take her for a bath) and we have a wooden floor.
I figured she would be afraid of the dark so I turned off all of the lights from the switches we have by the side of the hallway door so the only light on would be the one from the hallway. I said "Come girl!" one more time and that's when I heard her walking. But the steps were not comming from the big room, they were comming from behind me. I looked back and I saw Whoopy comming out of my bedroom.
As this could not be, because I had seen her pulling her leg underneath the table, I turned on all the lights and went to the living room, bended over and oh surprise... There was nothing underneath the table.
I don't know how is this possible. She would have had to pass by my side to go to the bedroom and make noise with her paws.
In other ocassion it happened to me that I saw my little brother staring at the phone while it was ringing when in fact he wasn't there, as I told in another story, he was the one making the phone call that I picked up... I think this might be the same.
What is the age difference between you and your brother? Not that it will make a difference with what I'm going to say but...
My youngest son (13) and my wife (38) share a 'connection' that allows for that 'back and forth' of her verbal questions/replies and his mental answers/questions. Makes me nuts when I ask him something and he looks at me, but doesn't say anything but seems to expect me to have heard his answer. There are times he swears he's answered out loud, but My wife, his older brother and sister and myself have to convince him he never spoke.
The 'living residual' theory seems to cover what you may have experienced with your dog. Thanks for sharing.
Respectfully,
