I have had 2 experiences that stick to my mind as "strange":
1. When I was 14, I was home alone, in the lower level of the family house. I was reading, everything was off. The door at the top of the stairs was closed. I thought I heard several strong knocks on that door. I walked from another room towards the bottom of the stairs to investigate. I then heard footfalls on the steps, as if someone was walking down them hurriedly. I froze, the footfall sounds continued down the steps towards me, and went silent about am arms length from me. I remember saying "WHOA!", more startled than scared, and just putting my hands straight in front of me, feeling a slight warm breeze, and then nothing. The heat was not on, there were few windows on that lower level, which were all closed and there were walls and doors between any windows and where I was.
2. About 25 years ago we were heading out to some event in the evening. It was a dark and stormy night
, lots of thunder, and the rain was pouring down. We were running late, and I was in a snappy mood towards DW and the kids. They were getting into the minivan when DW mentioned she had forgotten something. I told her to get the kids in the car, I would rush back into the house and get it. I'm upstairs locating the item when my cell phone rings. DW is calling from the car, she saying that "a big dog chased us into the van and won't go away, we're scared!". I find the item, come downstairs and outside. Sure enough, there is a big dog outside the side of the minivan. It looked to me like a Siberian Husky. When I come out the dog turns and runs towards me - but in a playful, wail wagging, non threatening way, jumps up and puts its front paws on me, seems to smile, then runs off down the driveway. I walk around the van and get into the drivers side, and the kids in the back row say "Look, the dog is behind us!" I check the rear-view mirror. The dog is sitting behind van, in the rain. I honk the horn, it does not move. I get out the van and approach it, and again it runs towards me in a friendly way, wagging its tail. I get back into the van, and it goes behind it again. This goes on for what seemed like a few minutes. Every time I get into the van it runs behind it, and there is no way for us to drive around it. Finally I approach it, it gives me a couple of friendly barks, and trots down the driveway out of sight into the night. The rain has let up a bit and the thunder has stopped. We drive down the driveway onto our street. leave. At an intersection a mile from our home there is an overturned tractor trailer. It seemed like it was trying to make a right turn onto our street and tipped over. we were the first car from our direction in the intersection and it was right in our path. Other people driving on the rood the truck was turning off off had stopped to check on things, the driver was out, walking around, and was okay. I back up and turn around, to take another route, I tell DW well, we are definitely going to be late. One of the kids says "yeah, that dog held us up". A few minutes later, DW turns me to and says "Would we have been at that intersection when that truck overturned, if it hadn't been for that dog?" I thought about it... and it was very possible. A week later, we attended a neighborhood party. A big topic of conversation was that stormy night as some folks had trees come down. I mentioned seeing a dog out in that area, a husky. No one else had seen it, nor did anyone we spoke to know of any home whom owned a husky in our neighborhood. DW and I regularly walk our neighborhood, several miles, we run into folks walking all kinds of dogs, but never anyone walking a husky. It could have been a coincidence... or not.
