Oh yeah, I think I get something similar when my sleep schedule gets very out of whack, or for some reason when I moved into my new house in January, though it went back to normal with time. (Potentially relevant features there: bedroom didn’t seem very separated from common areas, at first was sleeping on a pile of yoga mats instead of a bed, didn’t get out much.)
I think random objects might work in a similar way. e.g. if talking in a restaurant, you grab the ketchup bottle and the salt to represent your point. I’ve only experimented with this once, with ultimately quite an elaborate set of condiments, tableware and fries involved. It seemed to make things more memorable and followable, but I wasn’t much inclined to do it more for some reason. Possibly at that scale it was a lot of effort beyond the conversation.
Things I see around me sometimes get involved in my thoughts in a way that seems related. For instance, if I’m thinking about the interactions of two orgs while I’m near some trees, two of the trees will come to represent the two orgs, and my thoughts about how they should interact will echo ways that the trees are interacting, without me intending this.
No, never heard of it, that I know of.
