Have you seen something you cannot explain?

Describe it before you look at anyone else's. Your account is sealed and timestamped the moment you submit, so if it later turns out to match another report, the record shows your memory came first.

This is why the order matters. A description written after browsing a catalogue cannot be told apart from a description shaped by it. A description written before browsing can. That single difference is what turns a personal memory into something an outside analyst can weigh.

You draw what you saw, describe it in your own words, note the conditions, and place it in your visual field. The last question asks whether you had seen this kind of imagery before your experience, so records from people who came in unprimed can be counted separately.

You need an account to record one. The account is what stamps the record to you and fixes its place in the order. Your real name stays private and you are given an avatar instead.

Nothing from the catalogue is shown to you until after your own record is sealed. Only then are candidate matches offered.
