When my aunt was three or four, she was playing outside and a man came up to her. He introduced himself as her uncle, and asked if she'd like to learn to whistle. She said yes, and he taught her. They talked for a while, then he said goodbye and walked away.
My aunt ran inside and asked why she'd never seen Uncle Leslie before. My grandmother, surprised, asked how she'd heard about him. "Oh, he just came to teach me how to whistle."
As for me, I felt my mom's presence for a long time after she died. And, I'm pretty sure, Uncle Leslie came to visit a couple of times also. Hard to explain, but I knew who it was.
But why should we be surprised at this fact? I am not. That does not mean I want to see a ghost or be visited by a love done who is gone. I don't. Never have. And haven't been.
It just means that there is life after physical death, and it also means that there are demonic spirits in that "unseen world." Both of these facts are clearly taught in the Bible and, therefore, should not be a surprise at all.
Spooky? yes. Surprise? no.
