So, this might seem like nothing to others, but I'm going to write about it anyways.
I was levelling in TBC Anniversary server shortly before Midnight expansion released, less than a month before, and I had tried to go to Arathi Highlands because I was running out of quests in Hillsbrad Foothills. I got to the horde camp and accepted the quests and realized very few were close to my level, and most mobs outlevelled me. So I did the few I could do, and realized I had to leave for somewhere else to quest and return later. So that's what I did.
On my return, I was leaving the Horde camp, and was mounted running west, when I saw this person that had a username similiar to a person I used to know. I stopped to look for a moment out of curiosity then brushed it off as a coincidence and kept running west.
I had stopped to gather a herb for my alchemy then mounted up again and the person showed up right as I mounted and ran by me on their Blood Elf mount. This is exactly the same thing the person I used to know of the similiar name had done years before in 2015, only in person. This made me suspicious of who it was, but I had no way to confirm if it was them or not.
This person knew I played a rogue in 2015, a rogue named Toxicosis, and near where they ran by me on their mount were quests I was going to do, and in the area of those quests were farms for killing rogues called pathstalkers, yellow name cows, and the entire zone just felt slightly more populated by players than it had been the first time I was there, days earlier.
They didn't say or do anything to me so most people will brush it off as nothing, but the same thing happened again on my alt which I had sat in Undercity since both of those characters were Undead. Another Bloodelf by the name of Daria ended up cutting my alt off and getting in front of me and walking in front of me the same way. My character had been sitting there for days since it was my bank alt, I only had to level him so I could level my professions. I was running around levelling profs when the BE Daria cut me off same as this person above.
Daria is a show I watched as a kid. I haven't watched it in roughly 25 years.
It's not creepy, that she could somehow know to do this to me and which person is me, maybe, but it is odd, if nothing else.
