Okay that looks like a rock with a striation in it. They form in nature when a pebble is formed from a piece of rock that had several layers in it.

HERE are some more colourful ones.

Sometimes one of the layers is softer and crunbles leaving a "carved out" look.

You're probably just noticing it for the first time. Maybe it used to be up the other way and was disturbed by an animal or bird.

That looks natural. For proof chip it or break it in half to confirm the striation goes all the way through

& I do realize in hindsight it is a lot smaller than 4 inches. As the other poster suggested, I'm not trying to ascribe meaning to it.. just wondering if anyone is familiar with the potential symbology.

I grew up in a literal haunted house. All of my 4 older siblings had things happen, their friends would never want to sleep over after one time and would often leave early. Even my older brother when he was 16 with 4 other teenage boys had an apparition appear in the garage they were all sleeping and they ran out screaming.

My first memory with it was playing hide and seek when I was 4 and being under a desk, with my ear pressed against the wall. I heard a man's whispering. I didn't realize until I was 18 that where that wall bordered was directly adjacent to the closet one of my sisters had a shadowy figure stare at her from at night for years. She would often ask if any of us would sleep in there with her at night as she was terrified.

I am 100% serious, though being diagnosed later in life with bipolar type 1... Well, it is hard to be definitive about such things. I have another example if y'all are interested in hearing about it :|
