Statistics
Hyperphantasia is very vivid voluntary mental imagery—often at or above the 90th percentile on a given sense. In Imagination Index data, visual p90 is 100 and overall p90 is ~94. Hyperphantasia can occur in one sense or several; it is not the same as synesthesia.

Hyperphantasia describes very vivid voluntary mental imagery—often discussed for vision but applicable to any sense.
Scores at or above the 90th percentile fall in the high-imagery range we compare to hyperphantasia for that dimension.
Hyperphantasia is vivid imagination; synesthesia is involuntary cross-sense pairing. They can co-occur but are different phenomena.

Very vivid imagery can intensify worry, rumination, or distraction for some people—especially when intrusive imagery accompanies anxiety or trauma. For most hyperphantasics, the trait is neutral or beneficial. Awareness helps direct vivid imagery rather than being driven by it.
By cutoff symmetry, hyperphantasia is roughly as common as aphantasia at the opposite extreme—a few percent of the population per sense. Multisensory hyperphantasia (high across many senses) is rarer than single-sense hyperphantasia, just as multisensory aphantasia is rarer than visual-only aphantasia.
Modest gains in vividness are possible for some people through sustained practice (Image Streaming, vivid recall drills). Large shifts from typical to hyperphantasic vividness are uncommon. Profiles appear to be relatively stable traits with brain connectivity differences underlying extreme ends.
Mixed evidence. Hyperphantasia correlates with stronger episodic and autobiographical memory in several studies, but does not predict factual or working memory advantage. The benefit appears specific to imagery-rich memory tasks rather than general cognitive ability.
