I saw a black dog today, but no-one else did.
I saw a black dog today, but no-one else did. I was at work & I was talking to 2 friends. 1 was facing me the other was to my right. As I stood talking to these people I saw out of the corner of my eye a black dog run behind the friend who was standing to my right & launch itself at me (alongside her). As this happened her shoulder bag was seemingly knocked off her shoulder. I then lunged forward to move my friend out of this dog's way, scaring her as I did so. She asked me what I was doing, I told her about the dog & both my friends (& a customer of my store) asked "what dog?". I know I saw it. It was there.
Can anyone give me an explanation of what this could mean.
