Is it possible to be kin with something nonliving in nature? Like water or rocks or something like that?

seriousotherkin:

Logically speaking, it’s highly unlikely.  

Water doesn’t know it’s water. 
It has no experience of being what it is. 
So how can a person know what it’s like to be water?

A rock doesn’t know it’s a rock. 
It has no sense of being. 
So how can a person know what it’s like to be a rock?

I’m sure there are arguments, ways to rationalize or explain, but at the end of the day, if something has no self, no sense of self, no way to experience itself or it’s own existence, then how can a human being know, understand, what it’s like to be that thing?

Being otherkin has to do with a conflict between what you are on the physical level (human being) and what you are on the non-physical level (other). 
How do you compare your humanity to something that you can’t have any data on?

To top all that off, all water is interconnected. There isn’t a babbling brook that is made of water that is separate from all other water, because in the end all the water on this earth is one. 
Rocks too are merely part of the solid core of this planet, they aren’t truly separate entities. 
So, to indentify as a single rock upon this earth, or even a single mountain, is a little like looking at your body and identifying merely as a single fingernail, a tiny fragment of the whole of what you are. 

There are mythological beings who live in rocks and water, and many who are anthropomorphic personifications of the land in many ways, and arguably some of these can be considered kintypes, but to identify as one of these is distinctly different from identifying as water itself, or a rock. 

Most of those kin I’ve known through the years who at some point referred to themselves as inanimate natural objects or things later found that this term wasn’t accurate, for example those that had initially perceived as being water was more accurately an experience of being of water, from water, or in water. They still felt the same deep connection to water, but instead of stopping there they worked out why, in what setting, what their connection to water was and is, rather than assuming they were water.
