Wondrous Item, very rare (requires attunement)

When discovered, this book’s pages are all blank except for faint colorful patterns, as if stained by watered-down juices. When attuned, this book begins recording the visual experiences of its owner like a comic book but without words. It records these images automatically, recording up to twenty-eight days at a time, allowing anyone with the book to see images of people, places, and events from the owner’s perspective when the owner speaks a command word. After twenty-eight days, the front pages disappear as new pages in the back replace them. If the book is more than a mile away from the owner or the owner dies, the pages start erasing a day at a time until it’s blank again.

Wondrous Item, uncommon

Appearing as a small wooden box with sound receivers along its front and sides and a display lens on the top, it seems to be held together by magic and an unnecessary number of wood screws. The lens seems to fit loosely into its setting, apparently intentional. A switch on the back toggles the device’s operation. When shaken, the device produces an inordinate amount of rattling for its size. This device allows you, while holding it, to forgo mental visualization by producing sights, sounds, smells, and other sensations through its display lens. While active, the device understands descriptions that you hear spoken in a language you can understand and magically manifests them so that you can experience what is being expressed by the other party. The device functions by hearing the input, not telepathically, so its interpretations are literal and don’t take idioms into consideration. While active, the device is not discreet. Any attempts at hiding or stealth while the device is active are hindered by its occasional displays as it misinterprets ambient conversations as descriptions. Similarly, due to its construction, improperly securing and housing the device can cause it to make a ruckus when you run with it on your person, reducing or eliminating the possibility of stealth.

You are unable to reproduce one or more sensory experiences in your mind. Because of this, you’re unable to remember associated sensory experiences well or recognize people or objects that are less familiar. You can remember the feeling associated with experiences, places, and people. As a result, must succeed on a DC 15 Intelligence roll to accurately describe something you’ve perceived with that sense but have a +(IE) to describe it with a different sense. You also have a −(IE) penalty on Charisma (Performance) checks related to that sense due to challenges reproducing the sensory information, or you can forgo the penalty by taking 1 + (IE) × the usual amount of time to create it. But because illusion spells depend on mental perception or conjuring a mental depiction, you have a +(IE) bonus to all saving throws against illusion magic. If you have multiple traits, you may choose additional Aphantasia senses or Agnosia as one or more of them.

Real-world Examples

Aphantasia

Assistive Options

Assistance is learning to adjust how to remember, so when hearing a description, the listener imagines the associated feelings of such an experience, for example.
