What do you guys think was the intention with this? I recently had an episode of mania, and was behaving a bit oddly, but I confirmed with my mother (this was her condo I’m renting it) that it wasn’t here when she left and I’ve never seen it before :|
Definitely just a rock. Here’s a link where you can see lots of rocks with interesting markings, including a bunch that look like yours but with even more delineated markings.

OP if you’re thinking of this as anything other than just a regular rock then I’d suggest maybe getting in touch with your doctor
