There is a disease called Alice in Wonderland Syndrome. This causes patients to suffer massive migraines, while suffering visual hallucinations that alter their perception of what they see.
For example, they see objects as bigger or smaller than what they actually are, or even see them as upside-down. Because of this, people who have experienced this syndrome say that it was like living in a fairy tale. There is no known cure, but it is often temporary and will one day disappear like magic.
When you fall in love, the other person’s weaknesses seem smaller, their strengths seem bigger, and sometimes they turn your world upside-down. So is love like living in a fairy tale, or like suffering a disease?.
