As a Medium, Yes, I see, hear and feel things others normally don't. I have all of my life.
Many Christmases, I have had Phantom Visitors enjoying the Warmth of the Season with my Family and I at our Home.
Once, I was at an Apartment we used to Reside at in AZ.
I had awoke from a Nap, when I noticed something on our Tree Moving.
I looked over and realized it must have been a Child Spirit enjoying and playing with one of my Ornaments, a Stuffed Horse, in a shape indicating it was running.
I watched for a few moments.
It simply warmed my Heart and I smiled, laying there watching this small Spirit person playing as though the Ornament were a Toy.
I think it realized I was watching and it stopped.
I told the small one that it was welcome to keep playing, that I didn't mind at all.
It never did come back.
