Other forms: hypermnesias
Hypermnesia is the rare and remarkable ability to remember things in vivid, almost photographic detail. Someone with hypermnesia isn't likely to forget that rude thing you said last week, or even last year!
The most famous type of hypermnesia, the one that has been featured in some television shows and films, is the highly unusual ability to remember every detail of one's own life. It's sometimes referred to as HSAM: Highly Superior Autobiographical Memory. An adult with HSAM could recall every detail of a childhood birthday party, from the cake’s design to the exact words of a conversation. But some hypermnesia is more transient and specific, often associated with traumatic events, or perhaps induced under hypnosis. While uncommon, hypermnesia showcases the incredible potential of the human mind.
