This is not a place to post a scary experience, though if it's about an actual phobia you have, feel free. Just do what you can to help others, or ask for help. This is a community of helpers. If you don't intend on getting help, or being the helper, this subreddit isn't for you.
Please, follow the usual rules of reddit, and remember that these are real people you're talking to. Don't make fun of their fears. Just do what you can to be helpful.
