Autobiographical memory

How aphants describe (and often grieve) the absence of vivid, re-livable memories of their own past.

What people actually say

Childhood as a blank or "different life"

A recurring framing is that personal history feels remote, sparse, or belonging to someone else, often only retrievable through external props like photos or other people's stories.

"I don't. They can be jogged by photos or someone else describing the story, but for the most part, my childhood is like a different life." 2025 · t1_nb5i7vm ↗

"Most of my childhood is blank, except for a handful of memories from specific places I lived and a few that I may only remember because of photos and stories I've heard." 2023 · t1_jm09iw7 ↗

"Without photos, I'd likely forget most of the events in my childhood." 2025 · t1_mo0fokt ↗

Memories as facts, data, or log files

Many describe the format of recall in informational, propositional terms — they know what happened without re-experiencing it.

"My memories are like a log file or something like that. \"I've been there, I've seen this person\", etc. They are kinda like facts about the world, I don't feel any personal connection to them." 2019 · t1_elgisz1 ↗

"I guess yours are stored as jpeg and mine are stored as data." 2021 · t1_h6spsx1 ↗

"memories for me feel like facts, emotions, or bits of dialogue rather than 'movies.'" 2025 · t1_nb2a72u ↗

"Many people with SDAM remember their past as a series of facts and bits of knowledge, rather than memories of lived experiences" 2023 · t1_j5m1zuq ↗

What is preserved: emotion, vibe, spatial layout

When detail does survive, it tends to be affective or spatial rather than pictorial — a felt sense, mood, or floorplan.

"Mine are just facts, no visuals but I also feel a lot of emotion, like I feel the memories in my body" 2025 · t1_mh68afo ↗

"Mostly vibes. Like, really tho. I can generally remember what things looked like without being able to see a mental image of them. But along with that I often remember the feelings, moods, emotions, hopes, fears, worries, etc." 2025 · t1_nb1hxrz ↗

"I can remember the layout of my childhood home, but the only detail I remember a color and pattern for is the awful yellow corn flower wallpaper in the hall, I have no image of the corn flowers." 2020 · t3_hier9p ↗

Wishing they could get the past back

A minority of posts express longing — a wish to "see" their own past, and attempts at compensatory practices.

"I wish I could get back past memories. Sonce I know I have aphantasia, I've tried taking more picture. They help me re-live past experiences." 2025 · t1_mux6hzu ↗

"Same here! But I want a lot of things I cannot have, and of them all this one seems most likely to have unexpected side effects of changing who I am." 2020 · t1_ggd3btf ↗

Across the years

The descriptions look strikingly consistent. The 2019 "log file" framing, the 2020 "tag-cloud of concepts" home-layout posts, the 2021 "jpeg vs data" metaphor, and the 2025 "facts, emotions, or bits of dialogue" answers all converge on the same structure: propositional knowledge of one's past, often paired with emotional or spatial residue, but no replayable scene. Volume jumps sharply in 2025 (16 of 30 chunks), driven mainly by a single thread asking how aphants remember childhood, but the content of the answers does not shift — newer posters reach for the same metaphors that 2019–2020 posters used. The SDAM label appears explicitly from 2023 onward and gives some posters a name for what they've been describing all along.
