One horror story could be a nurse dealing with a family that constantly blames the nurse for every little thing that goes wrong with the patient's condition. For example, if the patient doesn't get better as fast as they expect, they accuse the nurse of negligence, even when the nurse is following all the proper procedures.
One horror story could be a medical student fumbling during a crucial surgery. The scrub nurse was passing the instruments, but the student was so nervous that he dropped the scalpel right on the patient's body (not causing major harm luckily). It was a nightmare moment for everyone in the operating room.
One horror story is when a skydiver's parachute didn't open properly. The cords got tangled up and they started free - falling at a terrifying speed. Fortunately, the reserve parachute opened just in time, but the few seconds of pure panic were unforgettable. Another is when a skydiver got caught in a strong updraft and was tossed around in the air like a rag doll, making it extremely difficult to control the descent.
Some people have reported psychological horror stories related to cryotherapy. For example, a person with claustrophobia was put into a cryotherapy chamber. The small, enclosed space combined with the strange cold environment made them panic. They felt like they were going to suffocate, and the whole experience left them traumatized and afraid to ever try cryotherapy again.
One of the horror stories could be about strange noises at night. People might have heard scratching on the walls or doors creaking on their own as if something was trying to get in. It's really spooky and can keep you up all night in fear.
A scrub nurse once had to deal with a surgeon who had a terrible temper. During the operation, the surgeon started yelling at everyone for the slightest mistake. The scrub nurse was constantly on edge, worried about making any error that would set off the surgeon. It made the whole surgical environment extremely tense and unprofessional. Also, there was a case where some contaminated instruments were accidentally brought into the sterile field, which could have led to a serious infection for the patient if not caught by the vigilant scrub nurse.
One horror story could be when a patient had an improper needle insertion during plasmapheresis. It led to severe pain and excessive bleeding at the site. The patient was in great distress as the procedure was supposed to be routine but turned into a nightmare.
Perhaps the most terrifying is when a collector discovers that a figure they bought as an original turns out to be a counterfeit. They might have paid a high price for it, thinking it was a genuine piece from myfigurecollection. And when they find out, it's not only a financial loss but also a blow to their collector's pride.
I heard about a babysitter who was taking care of a toddler. The toddler suddenly started talking to an 'invisible friend' and said the friend was angry. Then things in the room started to move on their own. The babysitter was so freaked out. Later, it was discovered that the house had some old wiring issues that were causing electrical glitches which made things seem like they were moving by themselves.
One of the scariest squatter stories I heard was about a family who came back from vacation to find squatters in their home. The squatters had trashed the place, broken furniture and left a mess. They also threatened the family when they tried to call the police.
One horror story is the excessive hazing. Pledges are sometimes made to do really dangerous stunts like jumping from high places into shallow water. Another is being forced to endure sleep deprivation for days, which can mess with your mental state.
