My reason is I've had my fair share of the real deal having gone through several surgeries and other similar stuff with my medical condition, and more often than not, I steer clear of that stuff for Haunt attractions and horror movies. I'll go with friends every once in a while just to spend time with them, but otherwise I don't care for it. It isn't anything bad like a trigger, but I normally don't care for that stuff.
For example, I marathon the Ghostbusters movies on the 31st. I listen to a lot of Halloween inspired orchestral music like Danse Macabre. Etc.
My Haunt visits are usually primarily for night rides on things I normally don't because I usually go for Beast, Diamondback or Banshee as my go-to night rides during the summer.
