Sure. There was a case where a fan made a really cool fan art inspired by Comic Con and shared it on Tumblr. But then some trolls on Tumblr started to make really mean comments, saying it was horrible and the artist didn't deserve to be at Comic Con. It made the artist feel really bad about their work.
A person shared their Comic Con experience on Tumblr, including some pictures of themselves with their favorite actors. But someone on Tumblr took those pictures and photoshopped them in inappropriate ways and spread them around. It was a nightmare for the person who originally shared the pictures.
At a Comic Con, there was a group that planned to do a collaborative Tumblr project related to the event. However, one member took all the ideas and ran with them on their own Tumblr, leaving the rest of the group feeling betrayed. This led to a big fallout within the group and was quite a horror story in the Comic Con Tumblr community.
Then there are the panel problems. You could be really excited for a particular panel, but due to technical difficulties, the audio or video doesn't work properly. Or the panel could be over - crowded and you end up having to stand outside and not be able to see or hear anything.
One horror story could be about a cosplayer who had their expensive costume stolen right at the Comic Con. They were so excited to show off their unique creation, but when they went to the restroom and came back, it was gone. Another could be a person who got lost in the huge crowd and couldn't find their way to the panel they had been waiting for months to see. It was a terrifying experience as they were pushed around by the throng of people.
One strip club horror story involves a power outage. The club didn't have a backup generator, and it happened during a busy night. There was chaos as the customers were left in the dark, and some took advantage of the situation to grope the dancers. The dancers were terrified as they couldn't see who was touching them. Also, there was a club that hired underage dancers unknowingly, and when the authorities found out, there was a huge scandal and the club was shut down immediately.
A person I know tried oil pulling during a very cold day. The oil got so cold in their mouth that it became really thick and hard to spit out. They panicked a bit because they thought it would get stuck in their teeth forever. Eventually, they managed to get it out, but it was a really unpleasant and somewhat horrifying experience for them. Oil pulling can have some unexpected and uncomfortable situations like this.
Sure. I heard of a halfway house where the food was constantly contaminated. There were maggots found in the bread one day. The place was clearly not being maintained well in terms of hygiene. The residents were getting sick and were very worried about their health. It was a nightmare situation as they were already in a vulnerable position trying to get their lives back on track.
The first disturbing horror story could be about a small town. Every few years, a child goes missing. The townspeople suspect a mysterious figure that lurks in the woods on the outskirts. No one has ever seen its face clearly. Another story is of a mirror. A woman buys an antique mirror. But when she looks into it, she sometimes sees a different face, a face full of malice. It starts to seem like there's something malevolent trapped inside the mirror. For the third story, there's an old cemetery. People who visit at midnight claim to see a ghostly figure hovering over certain graves, and they can feel a cold chill that seems to seep into their bones.
Sure. There was a Tumblr horror story where a user found an old, abandoned blog. The blog had posts that seemed to predict the future in a really creepy way. For example, it would describe events that happened the next day in detail. The user got really spooked when the blog started to mention things about them personally, like their daily routine and the people they knew. They quickly stopped looking at it.
Sure. A girl put on a new lace front wig one morning. Later that day, she noticed little bugs crawling on the wig! Apparently, it had some sort of insect eggs on it when she bought it. She was horrified and immediately threw the wig away.
Sure. There was this one person who had bulimia and they ended up with severe digestive problems. Their stomach lining was damaged from the constant purging, which caused intense pain during eating. It was really disturbing to see how much their body was suffering.
