Sorry I'm not sure of the relation to antibiotics, but Hypnagogia is something even aphantasics experience. It's typically more involuntary than not, so it's grouped with dreams rather than visual imagery/thinking.
Oh, that's interesting. Do you mean they experience visual hypnagogia? Because I'd say at the time I lost it, those visual experiences were the only ones I had, so it did seem distinct from any non-hypnagogic visualizations.
Also, I remember as a kid if I played video games I would see images of them when I closed my eyes. I don't think that happens now. Maybe those brain pathways got pruned....
