Even if your flashes seem unrelated, they will eventually reveal a meaning, or so I've found. It helps to write them all down (if you can find the time and inclination). By recording all of these type of instances I experience, I find that eventually I will see where the piece fits in the puzzle.

And it's so cool you "see" into wood grain! Me, too. I have a fair bit of grainy wood in my bedroom and it is just loaded with doods. And with hardwood floors...they are even on the floors. Ever there, ever watching. Lots of wolves.

What did you see? Any specific type of entities?
