Arachibutyrophobia: Fear of peanut butter sticking to the roof of your mouth

Phobias are much more than just being afraid of something. Almost all people feel afraid at some point, depending on their exposure to certain things or threatening situations. People with phobias, on the other hand, have a marked fear or anxiety about a specific object or situation that can lead to clinically significant distress. They can have an impairment in their ability to function in daily life, including socially or at work. Certain phobias are more common than others, including ones related to airplanes, elevators, or spiders; others are less so.

For example, it’s an uncomfortable feeling for everyone, but some people have a phobia involving fear of peanut butter sticking to the roof of the mouth. Some people can handle eating small amounts, but others avoid peanut-based products like peanut butter sauces and ice creams. It can be rooted in a broader phobia, like the fear of sticky textures or choking, or it can occur independently. If you think a fear of peanut butter sounds unusual, check out these 46 weird facts that most people don’t know.

Nostophobia: Fear of returning home

Home might be where the heart is for some, but others have the fear of returning home. These people might have experienced abuse there.

A study published in a 2018 issue of the journal Social Science & Medicine states that children who return home may alter a parent’s quality of life. This is probably because parents became used to independence after their children left. Therefore, when children enter the picture again, it can upset the dynamic.
