You said up above that you’ve never done psychedelics, so it makes sense that you’ve never experienced it. This is not a simple example of hyperassociation, it’s a classical case of psychedelic apophenia. If you spend just a few minutes browsing r/psychonaut, you’ll see if for yourself. I’ve also found that one can replicate it by drinking too much coffee. The connection between apophenia and psychedelics is well known.
