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.

And yet that doesn't mean that all extra associations and cognitions that occur on psychedelics are apophenic.
