The disorientation felt in a foreign country — the sense of being an outsider. Can be uncomfortable or exhilarating depending on the person.

The overwhelming urge to pinch or squeeze something because it's so cute. Also felt when seeing babies, puppies, or anything impossibly adorable.

A longing for home that no longer exists or never was. A nostalgia and grief for the lost places of your past, or a romanticized past.

The act of acquiring reading materials and letting them pile up without reading them. A common affliction among book lovers.

Vladimir Nabokov described it as 'a longing with nothing to long for, a sick pining, a vague restlessness.' It can range from mild longing to a deep ache of the soul.
