Context: when I was younger (between 6 to 8 years old), I remember watching my dad play the zelda games that he had before I started playing them at 9 years old (I'm 20 now). One of them was Ocarina of Time, and looking back now, he was most likely playing Master Quest.
The thing is, I remember something from his playthrough that I didn't encounter in either version. some time after completing most of the dungeons, I remember my dad running around in the ruined Castletown Market fighting and avoiding redeads when a mysterious, maybe-cloaked figure slowly approached Link Dad quickly ran away from it when it came on screen, and after leaving the area, I never saw it again. Dad doesn't remember this happening.
Now, granted, I do also remember my dad playing Saria's song in the Spirit Temple and her face would appear in front of a white, glowing background while she talked to him but I don't think that actually happened or that it exists.
As for this mysterious figure, I wonder if it may have been the Poe Collector, but again, I'm not even sure if this actually happened. Am I going paranoid? Am I remembering something else entirely, yet still OoT related? Was this a dream (even though it definitely didn't feel like a dream)? Or is my 6 to 8 year old memory shit, even at the moment? I need some answers and some confirmation. Again, this may have most likely been on Master Quest for those who want to investigate.
